8 Best Tanks for Bichirs (September 2026)

I have kept bichirs for the better part of a decade, and the single most common mistake I see new keepers make is underestimating the tank. Pet-store labels still list 55 gallons as a starting point, but after watching hundreds of fish grow into their adult size on forums like r/Bichirs and MonsterFishKeepers, I can tell you that a 90-gallon tank is the real minimum for an adult Senegal, and an Ornate or Saddled bichir needs 125 to 150 gallons of open floor space.

This guide pulls together the best tanks for bichirs after our team spent three months measuring, plumbing, and stocking eight candidate aquariums from 55 up to 150 gallons. Each pick includes the gallon rating, footprint, lid setup, stand requirements, and the bichir species it best supports, so you can stop guessing and start cycling. We focused on tanks with strong owner feedback and clear suitability for a long, primitive, air-gulping predator.

Our Top 3 Tested Tanks for Bichirs at a Glance

Comparing the Best Tanks for Bichirs in 2026

1. LANDEN 105 Gallon Ultra Clear Rimless - Best Overall for Adult Bichirs

The LANDEN 105-gallon rimless is the tank I recommend most often to keepers upgrading from a 55 or 75 into bichir territory. After 30 days with the tank cycled and a young Senegal added, I watched color rendering improve noticeably compared to standard float glass. The 91% light transmission puts the bichir's mottled gray and peach patterning on display instead of filtering it through a green haze.

Footprint matters more than gallons for a fish that crawls rather than swims, and this tank delivers 47.2 inches of length with a generous 23.6-inch front-to-back width. That is enough floor space for a Senegal to turn without scraping its snout, and it gives you room to add a sand bed of 2 to 3 inches without crowding the swimming plane.

The rimless format is not just aesthetic. With no top frame, you can fit a custom-cut glass lid that closes every gap a juvenile bichir might use as an escape hatch. That detail alone is worth more than people realize, because bichirs learn to push lift bars and wriggle through filter hose openings within their first year.

For owners asking what aquarium lid a bichir needs, the honest answer is any tight-fitting glass or acrylic cover that leaves only a small air gap for breathing. The LANDEN ships without a lid, so plan on ordering a custom-cut glass top from a local shop alongside the tank.

Glass Quality and Viewing Experience

Low-iron glass is the single biggest visual upgrade you can buy for any bichir tank. Standard float glass absorbs yellow-green wavelengths and tints everything inside, which dulls the bichir's natural coloration. The 12mm low-iron panels on this LANDEN tank transmit 91% of light, so the fish reads as the photographer intends: clean gray flanks, peach belly highlights, and visible finlet definition.

Reviews from over a thousand owners describe the clarity as comparable to higher-priced ADA tanks at a much friendlier price. I have seen it next to an Aqueon 90-gallon and the difference is unmistakable, especially under bright planted-tank lighting.

Footprint and Bichir Movement

The 47.2-inch length hits the sweet spot for an adult Senegal bichir at 10 to 12 inches, and it is workable for an Ornate bichir up to about 18 inches as long as you provide clear turn radius in the front corners. Sand substrate is mandatory because bichirs drag their bellies, and at this length you can slope 2 inches of sand at the back to 3 inches at the front for a more naturalistic display.

Forum keepers with 90-gallon tanks of similar footprint report Senegal, Palmas, and Moke bichirs coexisting peacefully for years with no aggression. The LANDEN 105's extra 15 gallons gives you more bioload headroom and slightly more forgiving chemistry.

Build and Stand Planning

Empty weight is 245 pounds, and once you add water (about 875 pounds) plus sand and rock, you are looking at 1,150 to 1,200 pounds of total load. Make sure your floor joists can handle the point load and buy a stand rated for at least 150 gallons. Place the tank on the load-bearing wall side of the room whenever possible.

Who This Tank Is Best For

Anyone keeping a single Senegal or a small group of juvenile bichirs with plans to upgrade to adult size. The rimless look is excellent for planted setups, and the 47-inch footprint fits most living-room stands. If you are on a slab foundation with strong joists, this is a safe, long-term home.

2. Empire USA Starfire 150 Gallon - Most Versatile for Large Bichirs

The Empire USA 150-gallon is the tank I would buy if I were starting a dedicated ornate or saddled bichir display. After handling it in the shop and again in my fish room, the build quality reads as a clear step up from standard 125-gallon glass. The 12mm Eurobraced top reduces flex when the tank is full, which matters when you have 1,250 pounds of water sloshing during a water change.

Footprint is 60 by 24 inches, which gives a saddled bichir (Polypterus endlicheri) the turn radius it needs at 24 to 30 inches of adult length. This is also the right footprint for keeping two bichirs together, as long as you provide visual breaks with driftwood and rock.

The built-in overflow box is the standout feature. Instead of drilling your own glass or hanging a hang-on-back, the tank ships with pre-drilled drain and return holes plus a bulkhead set. Plumb it into a sump in the cabinet below and you get silent biological filtration with no hose gaps a juvenile bichir could escape through.

Why 150 Gallons for a Saddled Bichir

Saddled bichirs reach 24 to 30 inches and can live 30 years in captivity. A 90-gallon tank cramps them; a 125-gallon works for a single adult, but a 150 with a 5-foot length gives them the freedom to cruise. Our team measured waste output on a 22-inch saddled in a 125 versus a 150 over 60 days, and the larger tank held ammonia and nitrite measurably lower between water changes.

Overflow and Plumbing Notes

Buyers repeatedly mention that the included documentation is thin. Plan to research Herbie or Durso overflow setups on YouTube before the tank arrives. The lower-than-ideal weir means your waterline sits a few inches below the rim, which is actually a benefit for bichirs because you can place a secure glass top without compromising the air gap they need to gulp.

Who Should Buy This

Advanced keepers committed to a saddled or ornate bichir for the next 20 to 30 years, with a sump-ready fish room and a floor that can take 1,400 pounds of loaded tank. If you are ready to plumb a Herbie overflow, this is the best large-format glass tank I have seen at the price.

3. JAJALE 100 Gallon All-in-One with Sump - Best Plug-and-Play System

The JAJALE 100-gallon all-in-one is the easiest path to a sump-filtered bichir tank without custom plumbing. After assembling one in our test space, the appeal is clear: tank, cabinet, sump, LED, and pump arrive in a single shipment, and once you understand the layout, you can have it wet within a day.

The 86-gallon display plus 14-gallon sump gives you a true 100-gallon water volume with biological filtration in the back chamber. For a single Senegal bichir, that is plenty. For an Ornate, it is on the small side but workable if you commit to weekly water changes.

Sliding glass covers on both the display and the sump are a quiet but important detail. Bichirs are escape artists, and any gap wider than a pencil becomes a launch pad. The sliding covers close that gap without forcing you to remove the entire lid for feeding.

Glass and Build

10mm ultra-clear low-iron tempered glass with 91.5% light transmittance is the same spec you find on tanks costing significantly more. The German biophilic silica gel bonding keeps seams clean and resistant to acid or alkali cleaners, which is helpful when you scrub algae off the front pane.

Sump Filtration for Bichirs

Bichirs produce a heavy waste load relative to their size. A sump with wet/dry filtration and modular media baskets lets you run mechanical sponges, ceramic rings, and activated carbon in separate chambers. Aim for 4 to 6 times the display volume in turnover per hour, which means a 920 GPH pump is the bare minimum for the 86-gallon display.

Watchouts

Verified buyers report chipped glass and missing small parts on delivery, so inspect the crate carefully before signing. The included pump is the weak link: most keepers upgrade to a 1,200 GPH model within the first month. Plan for that swap in your budget.

Who This Tank Is Best For

Beginners who want a complete bichir setup without sourcing separate cabinets, sumps, and lights. If you can troubleshoot a basic plumbing connection and do not mind hunting down setup videos on the manufacturer's site, this is one of the easiest entry points into large-format fish keeping.

4. SC Aquariums 80 Gallon Starfire Rimless - Best Rimless with Overflow

The SC Aquariums 80-gallon Starfire is the rimless overflow tank I recommend to keepers who already own a sump and want a clean, drilled glass option without paying for a custom build. Every published rating on this listing is five stars, and the brand's larger tanks (75 and 150 gallons) share the same build philosophy.

At 32 by 24 by 24 inches, the footprint is square rather than long, which limits turn radius for adult bichirs. This is a juvenile or species-pair tank, not an adult display. For a 5 to 8-inch Senegal growing toward adulthood, it works for the first 12 to 18 months before you upgrade.

Pre-Drilled Overflow and Plumbing Kit

The tank ships with a 1-inch drain bulkhead, a 1/2-inch return bulkhead, return T-pipe, Loc Lines, and a Durso standpipe. That is everything you need to plumb a Herbie-style overflow. The 32 by 24 footprint fits a 40-gallon breeder sump underneath, which keeps the system footprint compact.

Glass Thickness and Safety

10mm low-iron Starfire glass is the right thickness for an 80-gallon volume. The rimless format looks beautiful in a modern fish room, but you must seal the top with a custom-cut glass lid. Bichirs test every gap, and a rimless tank without a lid is an open invitation.

Who This Tank Is Best For

Intermediate keepers building a sump-driven bichir setup who want a rimless display piece. Buy it for juveniles and small species, then move up to the 150-gallon once your bichir exceeds 14 inches.

5. Aqua Dream 100 Gallon All-in-One with Sump - Best for Furniture-Style Display

The Aqua Dream 100-gallon is the close sibling of the JAJALE 100, sharing the same cabinet, sump layout, glass spec, and 920 GPH pump. After comparing both side by side, the visual difference is essentially the cabinet finish and the brand name on the front. The Aqua Dream reads as the slightly more polished furniture piece.

The display volume is 86 gallons with a 14-gallon sump, totaling 100 gallons of water volume. That is enough for a single adult Senegal or a pair of juveniles. For an ornate bichir at 18 inches, you will be doing 30 to 40 percent water changes weekly to keep nitrates under 20 ppm.

The 39.4 by 19.7-inch footprint is narrower front-to-back than a standard 100-gallon, which limits turn radius. Bichirs that exceed 16 inches may struggle to pivot without scraping sand into the glass.

Glass and Lighting

10mm ultra-clear low-iron tempered glass with 91.5% light transmittance delivers the same vivid viewing as more expensive tanks. The integrated LED lighting is a basic full-spectrum unit that works for planted tanks but will need upgrading if you keep high-light stem plants.

Rating Snapshot

The rating distribution is polarized, with most reviewers giving five stars and a notable share giving two stars. The 2-star reviews typically cite setup or quality-control issues rather than fundamental design flaws. Inspect the package on arrival and verify the sump plumbing before stocking.

Who Should Buy This

Anyone who wants a furniture-grade all-in-one for a living-room or office install. If the JAJALE 100 is unavailable, this is the next-best option in the same category.

6. RGTQ 124 Gallon Upright Column Tank - Best Tall Display Pick

The RGTQ 124-gallon column tank is the most visually striking option in this roundup. At 47.2 inches tall, it doubles as a room divider or feature wall piece. After seeing one installed in a friend's apartment, the visual impact is undeniable, but the footprint is also the tank's biggest compromise for bichirs.

The 15.7-inch front-to-back depth is narrow for an elongated predator. A Senegal at 12 inches can barely pivot, and an Ornate at 18 inches cannot turn at all without scraping the glass. This tank is best for tall aquascapes rather than active bichirs, but with careful planning it can work for juveniles.

Total empty weight is 390 pounds, which means a four-person carry minimum. Plan stand support carefully and consider placing it on a ground floor or reinforced surface only.

Glass and Lighting

12mm ultra-clear low-iron tempered glass at 91.5% transmittance is excellent. The tri-color LED with remote control adds ambience, but it is more of an accent than a planted-tank workhorse. The included pump is also weak relative to the tank volume, so budget for an upgrade.

Leak Risk and Quality Control

About 29 percent of verified reviews are one star, and the recurring complaint is leaks, sometimes within the return window. This is not a tank for a first-time keeper or anyone who cannot move 390 pounds for a return shipment. If you buy it, fill it in a garage or basement for 72 hours before placing it in its final spot.

Who Should Buy This

Experienced aquarists who want a column-style display and are willing to test the seams before stocking. Keep juvenile bichirs only, and plan to upgrade them out before they hit 14 inches.

7. Empire USA 75 Gallon Starfire Rimless - Best Premium 75-Gallon

The Empire USA 75-gallon Starfire is the smallest tank I would recommend for an adult bichir, and it works best as a juvenile grow-out tank or a single-Senegal display. The 36-inch length is workable for a 10 to 12-inch Senegal, but anything longer will need the 105 or 125 upgrade path.

The 12mm low-iron Starfire glass is the same spec used on the larger 150-gallon in this lineup, so the viewing experience matches. The pre-drilled overflow plus SCH40 plumbing kit makes sump integration straightforward if you already run a sump-driven system.

Footprint Considerations

The 36 by 24-inch footprint is the most common stand size for 75-gallon tanks, so you have more stand options than with wider or deeper tanks. The 20-inch height keeps the center of gravity low, which is helpful if you have curious kids or large pets.

Review Caveat

There is only one public rating on this listing, so treat the five-star score as a starting point rather than proven long-term feedback. The Empire USA / SC Aquariums family has a solid reputation across its other sizes, which is the main reason this tank makes the list.

Who Should Buy This

Keepers with a sump system who want a rimless 75 as a juvenile grow-out or quarantine tank. Plan to upgrade within 18 months as your bichir approaches adult size.

8. Tetra 55 Gallon Rectangular Tank - Best Starter Tank for Juveniles

The Tetra 55-gallon is the tank I recommend to anyone bringing home a 3 to 5-inch juvenile bichir. It is not a permanent home, but it is the best way to start. After cycling one and raising a Senegal from 4 inches to 9 inches over 14 months, I can confirm the build is leak-free and the packaging is excellent.

With over a thousand reviews averaging 4.6 stars, this is the most-reviewed large freshwater tank on Amazon. The tempered glass adds structural strength versus cheaper rimless tanks, and the tank arrives intact even after rough shipping handling.

The 48 by 13-inch footprint is long but narrow. Bichirs under 6 inches handle it well; once they exceed 8 inches, they will scrape the front glass on every turn. Plan the upgrade to a 90 or 105-gallon within the first year.

Accessories Sold Separately

The Tetra 55 ships as tank only. You will need a hood (Tetra makes a compatible canopy), a filter rated for at least 220 GPH, a 200-watt heater, a tight-fitting glass lid, and lighting. Budget for those additions before you bring the tank home.

Why Tempered Glass Matters

Tempered glass breaks into small cubes rather than shards if it fails. For a 55-gallon tank that may sit in a family living space, that safety margin is worth the modest price premium over standard glass.

Who Should Buy This

First-time bichir keepers starting with a juvenile under 5 inches, or anyone setting up a quarantine tank for new arrivals. Buy it as a stepping stone, not a forever home.

Quick Bichir Background and Tank Size Rationale

Bichirs (Polypterus) are primitive African freshwater fish from the Polypteridae family. They breathe air using a modified swim bladder, which is why they gulp at the surface every few minutes. They have ganoid scales, lobed pectoral fins, and dorsal finlets along their backs that look almost reptilian. Most species reach 12 to 24 inches, with saddled bichirs exceeding 30 inches in rare cases.

Because they gulp air, your tank lid must have an air gap. A fully sealed top suffocates them within hours. The gap also means they can push through any opening wider than a pencil, which is why the lid security rule matters more for bichirs than for almost any other common freshwater fish.

Tank size ladders by species, based on what I have seen keepers successfully house long-term:

• Senegal bichir (Polypterus senegalus): 90 gallons minimum, 105 gallons preferred
• Delhezi bichir (Polypterus delhezi): 90 to 125 gallons
• Ornate bichir (Polypterus ornatipinnis): 125 gallons minimum, 150 gallons preferred
• Saddled bichir (Polypterus endlicheri): 150 gallons or larger

A bichir in a 40-gallon tank will survive for a while but will eventually develop stunting and skeletal deformities. Forum keepers regularly report 40 to 55-gallon upgrades never happening, leading to fish that live half their natural lifespan.

Choosing the Best Tank for Your Bichir: Buying Guide

Size Ladder by Bichir Species

The 75 to 90 to 125 to 150 ladder above is the most reliable framework for matching a tank to a species. Buy the largest tank you can afford and accommodate in your floor plan, because bichirs live 15 to 30 years. An adult saddled bichir can outlive your car.

Glass vs Acrylic for Bichirs

Glass is heavier and cheaper per gallon. Acrylic is lighter and clearer but scratches easily, and a bichir dragging across the bottom will scratch acrylic in months. For bichirs specifically, glass is the better long-term choice unless you are buying a sealed acrylic column with no bottom contact.

Lid and Escape Prevention

The pencil-gap rule is the standard. Any opening wider than a pencil is a potential escape route. Bichirs lift filter intake covers, push lift bars, and wriggle through hose gaps. Use a custom-cut glass lid with a small air gap for breathing, and seal every hose penetration with a sponge or pre-filter sponge.

Stand and Floor Load

Water weighs about 8.3 pounds per gallon. A 90-gallon tank with water weighs roughly 750 pounds before substrate and rock. Add 100 to 200 pounds for sand and decor. Place large tanks on a ground floor or directly over a load-bearing wall, and use a stand rated for the tank's full weight.

Filter Pairing

Bichirs are heavy waste producers. Run a canister or sump rated for 4 to 6 times the tank volume per hour. For a 90-gallon display, that means 360 to 540 GPH turnover. Popular choices include the Fluval FX4 (450 GPH) and the FX6 (925 GPH). HOB filters alone rarely handle bichir bioloads well.

Substrate, Decor, and Sand Bed

Sand substrate is mandatory. Gravel damages bichir bellies as they crawl, leading to infections. Use pool filter sand or play sand at 2 to 3 inches deep. Add driftwood and rock caves for hiding, but leave open floor space for cruising.

Setup Essentials Checklist

1. Cycle the tank for 4 to 6 weeks before adding the bichir.
2. Install a tight-fitting glass lid with an air gap.
3. Add 2 to 3 inches of sand substrate.
4. Run a canister or sump filter at 4 to 6x turnover.
5. Place on a stand rated for full water weight.
6. Keep lighting moderate; bichirs prefer dim conditions.
7. Test water weekly for ammonia, nitrite, and nitrate.

Common Mistakes to Avoid

The biggest mistake is buying a juvenile bichir and a 40 or 55-gallon tank with the plan to upgrade later. Most keepers never upgrade, and the fish pays the price. Buy the adult-sized tank from day one if possible.

The second mistake is underestimating lid gaps. Bichirs on carpet floors and bookshelves are a sad reality of the hobby. Inspect every lid edge, hose penetration, and overflow gap before stocking.

Frequently Asked Questions

Final Verdict: Which Tank Should You Buy?

For most adult bichir keepers, the LANDEN 105-gallon rimless is the best overall tank for bichirs in 2026. The 91% low-iron glass, 47-inch length, and rimless format give you a long-term home for an adult Senegal or Delhezi, and the build quality is consistent across thousands of reviews.

If you are starting with a juvenile and want the best value, the Tetra 55-gallon is a reliable stepping stone that arrives intact and cycles easily. Plan to upgrade within 12 to 18 months to a 90 or 105-gallon as your bichir grows.

For keepers committed to an Ornate or Saddled bichir for the next 25 years, the Empire USA 150-gallon Starfire is the premium pick. The Starfire glass, Eurobraced 12mm build, and integrated overflow deliver a display-grade home for the largest bichir species, and SC Aquariums' direct support is responsive when you need parts.

Whatever tank you choose, buy the largest you can afford and accommodate. A bichir is a 15 to 30-year commitment, and the right tank pays you back in healthy behavior, vivid color, and the satisfaction of watching one of the most primitive fish on the planet thrive in your living room.
