Crenicichla compressiceps

Crenicichla longhorn or Crenicichla compressionis naturally inhabits the lower basin of the Rio Tocantins in Brazil. The fish stay in areas with a substrate consisting of a mixture of sand and stones. Despite its small size, this fish is predatory and will captivate you with its interesting behaviour and breeding.

The body of Crenicichla compressiceps has six to eight narrow yellow vertical stripes, which sometimes extend to the dorsal fin. The main body colour is greenish yellow. There are black vertical stripes on the caudal fin and part of the dorsal and anal fins. Males are larger than females and have larger and sharper fins, while females are rounded. The size of fish in the wild is less than 10 cm, but in aquariums they reach 8 cm.

Crenicichla compressiceps are extremely aggressive, which makes it difficult to keep them together. Use a large aquarium of 160 liters and provide multiple shelters, otherwise the male will constantly pursue the female and as a result, can beat her to death. Can be kept in a common aquarium with other larger cichlids, all that is half the size, will be for Krenitsihla longhorn food.

Use coarse river sand and stones of various sizes as substrate, forming numerous caves as well as snags. Numerous plants should also be planted around the perimeter of the aquarium so that the female can hide from the male. For maximum approximation of aquarium conditions to natural at the bottom, it is desirable to place pre-dried leaves of tropical almonds, which have antiseptic and antifungal properties and will keep the spawning fish.

Water parameters: temperature 24-27° C, hardness dH 2-8°, pH 5,0-6,8. Requires quality filtration, aeration and a weekly change of 1/3 of the aquarium water with fresh. Nitrates in the aquarium water should be kept to a minimum.

The long-eared Crenicichla compressionis is a typical predator. In the natural environment, it feeds on small crustaceans and insect larvae they find among rock crevices. In an aquarium, the fish can be fed with earthworms, ground shrimp meat and bloodworms. The fish can also be accustomed to granular, sinking to the bottom, food. It is advisable to occasionally feed the fish with minced meat from shrimps, sea fish fillets, spinach and a few green peas. Feed the fish once or twice a day.


For breeding fish, it is best to buy a large group of young fish. When they begin to mate need to keep only 1-2 pairs, and the remaining fish be removed. This is due to the fact that the spawning pairs occupy a large area in the aquarium and simply not enough space for all. Too many pairs will lead to constant conflict between them.

Spawning stimulate increased feeding live food, as well as raising the water temperature to 28-29° C and lowering Ph.

Spawning is preceded by a mating dance, after which the pair dig a hole in the ground or choose to spawn in a plastic tube inserted into the substrate.

Larvae hatch after 4 days, and after about 2 weeks fry leave the incubation hole and begin to swim freely.

Artemia nauplii are the starter food for the fry. It should be noted that the parents take care of the fry for quite a long time.
