Red Terror Cichlid Behavior and Temperament
Red Terror Cichlids are aggressive and should only be kept with other aggressive fish. They are not recommended for beginners.
Red Terror Cichlids will often establish a hierarchy in the tank. The most aggressive fish will be at the top of the scale. The order will determine who gets to eat first and who gets the best hiding spots.
If you keep more than one Red Terror Cichlid, you should provide plenty of hiding spots. This will help reduce aggression. Red Terror Cichlids are also known to be fin nippers. They may nip the fins of other fish in the tank.
You can provide hiding spots and reduce aggression by keeping your Red Terror Cichlid in a tank of at least 50 gallons. It would help if you also offered plenty of rocks and caves for them to hide in.
False Red Terror
These fishes are often confused with the much rarer Mayaheros urophtalmus species, also known as the False Red Terror. These fish are similar in size and shape, and they both have a red coloration with dark vertical stripes.
The easiest way to tell these two species apart is by looking at the fins. The False Red Terror has black edging on the fins, which is not present on the Red Terror Cichlid. In addition, the False Red Terror has a more rounded body shape, while the Red Terror Cichlid is more compressed.
False Red Terror Cichlids are sometimes sold as true Red Terror Cichlids in pet stores, so be sure to ask the seller which species you are getting before making a purchase.
Red Terror Cichlid Breeding
Red Terror Cichlids are monogamous and will pair for life. They are also known to be protective of their eggs and fry. Forcefully pairing two Red Terror Cichlids together can result in death, as they will fight with each other.
To encourage breeding, you should increase the water temperature to 86 degrees Fahrenheit. You should also provide plenty of hiding spots for the female to lay her eggs. The male will then fertilize the eggs.
The female will lay up to 500 eggs and hatch within four days. The fry will be free swimming after 5-7 days.
You should feed the fry live foods such as brine shrimp or daphnia. You can also feed them crushed flakes or pellets.
You should remove the parents from the tank after the fry is free swimming. The parents may eat the fry if they are left in the tank.
If you want to keep the fry, you should provide plenty of hiding spots for them. You should also perform regular water changes to keep the fry healthy. The fry will reach maturity in 6-8 months.
Red Terror Cichlid Care Guide
Caring for these fish is not complex, but providing them with a large tank is essential. They need at least 180 gallons, and more is better. The tank should be decorated with large rocks, driftwood, and some floating plants.
These fish like to dig, so a layer of sand or gravel on the bottom of the tank is also recommended. You must change the tank water often to keep the environment clean. The tank will need plenty of filtration and maintenance.
Red Terror Cichlids are not picky eaters and will accept most types of food. They should be fed various foods, including pellets, flakes, freeze-dried foods, and live or frozen foods. Feed them several times a day in small amounts to eat all their food before it sinks to the bottom of the tank.
These fishes are aggressive and must be kept with other large, aggressive fish. They can be controlled with other cichlids and catfish, barbs, and danios. Avoid keeping them with smaller fish, as they may become snacks.
