Behaviour description

In the captivity Crenicichla anamiri will show generally a peaceful behaviour, but may prey on small fish and be territorial with conspecifics. These dwarf pike cichlid will do well in groups so long as adequate cover and hiding places are available in the aquarium.

Some dried leaves could be placed on top of the substrate to create a more natural feel, and as these gradually decompose, they will release tannins that will not only help to acidify the water, but will also bring out the best colours of the fish – these leaves will require periodic replacement.

Sexual dimorphism

This species of pike cichlid presents a sexual dimorphism, where the females are smaller; the males are bigger with more pointed fins.

Crenicichla anamiri is distinguished from all congeners except C. notophthalmus, C. regani, C. urosema, and C. virgatula by having serrations on supracleithrum (vs. absence) – a bone of the pectoral girdle situated dorsal to the cleithrum. It differs from from C. notophthalmus and C. regani by having a black vertical elliptic blotch centrally positioned at caudal-fin base (vs. presence of ocellated blotch dorsally on caudal-fin base). It can be separated from C. regani, C. urosema and C. virgatula by having two to four rows of teeth in both jaws (vs. more than four rows); from C. virgatula and C. urosema also by the presence of vertical bars on the caudal fin (vs. absence).

Nutrition in Nature

In the wild, Crenicichla anamiri usually feed on small fish, shrimp, worms, and most meaty animals.


Breeding tank set-up
The aquarium for these pike cichlids can be decorated with some driftwood, stones, floating plants or places that provide shelter, as these fish prefer to hide and do not like intense lights.
Nutrition parents

In the aquarium this smal predators will accept insects, other invertebrates, small fish, frozen & prepared foods.
