Crenicichla notophthalmus



The Crenicichla notophthalmus lives in the Amazon basin, South America. The fish stay in quiet backwaters and forest streams that run through forested areas. They prefer to stay in shallows with sandy bottom. Fish should only be kept by trained aquarists. They are relatively rare fish among aquarists and not often available for sale.

Crenicichla notophthalmus has a brownish or yellowish body with a whitish-brown belly. The eyes are large, dark red. A broad longitudinal band of brown runs down the body from the muzzle through the eyes to the caudal fin. There are 11-12 short dark spots on the upper back. The dorsal fin is broad and extends from the head to the root of the caudal plumage. The dorsal plumage has a large black spot with a white-red rim. Males are slightly larger than females. The females have a dorsal fin with a white rim. They also have a rounded abdomen, a pinkish body and a dark spot on the dorsal fin. The size of fish in the wild reaches 40 cm, in aquariums, they usually do not exceed 15 cm.

Crenicichla notophthalmus

The Crenicichla notophthalmus is a territorial and predatory fish. Although these fish belong to the dwarf pike, they are much less aggressive. These fish can be kept in a common tank with other medium- and large-sized cichlid species, as well as catfish and other large fish. The Crenicichla oculi form strong pairs and are excellent parents. They spend most of their time at the bottom.

The fish require an aquarium with a length of about one meter and a volume of 170 litres. A sandy substrate, preferably in darker colours. Large flat stones and snags are placed at the bottom. Fish are indifferent to plants, so this is a role of your preference to plant them or not. Furthermore, it is important to consider the fact that large crustaceans often burrow under the roots of the plants, so if you do decide to plant shrubs, care must be taken to protect the rhizomes from the fish, e.g. by surrounding them with stones. Floating shrubs, e.g. salvinia or pistia, which recreate a subdued atmosphere that is as close to nature as possible, will solve the plant problem in most cases. It is advisable to keep a fish group of 6-7 fish, predominantly males.

Water parameters: temperature 24-27° C, hardness dH 4-20°, pH 6.5-7.5. Need aeration, filtration and weekly replacement of ¼ of the aquarium water with fresh. It is desirable to create a small current of water in the aquarium.

Their natural diet consists of small fish, shrimps, earthworms and insect larvae. The fish also like to eat ground beef and flake food. Feed the fish once a day, but make sure they are not overfed.

Reproduction

Krenitsihlata eyeball lays eggs in various hidden corners of the aquarium, usually in caves between the rocks and often the clutch can not be seen. Spawning is stimulated by increasing the water temperature to 28° C and abundant feeding. The female takes care of the clutch, while the male protects the spawning area from uninvited fish.

The larvae hatch after 3-4 days, and after another three days they begin to swim and feed. The fry are quite large and from the first days of life can eat Artemia nauplii. The fry are fed 4 times a day.

Crenicichla notophthalmus

The Crenicichla notophthalmus has a lifespan of about 7-8 years.
