This species can adapt to a wide range of water hardness and pH levels, making them one of the most versatile fish you can keep.

Providing a healthy environment for your Clown Loach is still essential. Here are some tips on how to do that:

Clown Loach Tank Size

Clown Loach should be kept in a tank of at least 100 gallons. Remember, they can grow up to 12 inches long, so you'll need a tank to accommodate their size.

You'll need an even larger tank if you're keeping more than one Clown Loach. Groups of 3 or more Clown Loaches should be kept in a tank of 100 gallons or larger.

However, we recommend keeping only one per tank to prevent them from becoming stressed.

Clown Loach Water Parameters

The most important thing to remember when setting up your tank is to provide a healthy environment for your fish. This means keeping the water parameters within their preferred range.

Clown Loaches like soft to medium water in hardness and pH levels of 5.0-8.0. They can adapt to a broader range of conditions, but it's best to keep them in water that matches their natural habitat as closely as possible.

Water Temperature: Like most fish, Clown Loach prefers water temperatures of 75°-86°F.

Water Changes: It's important to keep up with water changes to maintain the health of your fish. We recommend changing 25-50% of the tank water every week.

It's also very important to perform a regular water test to ensure the water parameters are within the preferred range. Use a reliable test kit to test ammonia, nitrite, and pH levels.

Clown Loach Filtration

Clown Loach needs a sound filtration system to keep the water clean and healthy. We recommend using a filter that can turn over the entire volume of the tank at least 3 times per hour.

A good filter will help keep the water parameters in check and also help reduce the amount of maintenance you have to do on the tank.

Some of the famous filters are:

  • Eheim 2217: These filters are German-made and some of the industry's best. They come with various filtration options, including mechanical, chemical, and biological filtering.

A good decoration will help make your tank look more natural and provide your fish with a place to hide.

Some of the famous decorations are:

  • Driftwood
  • Rocks

Other Tank Accessories
