Kribensis

A common aquarium fish

This fish has many names, including kribensis, krib, rainbow cichlid and purple cichlid. This is one of the most common fish species sold in aquarium shops. Some reasons for this are that it is easy to care for, functions well with many other fish, and is not fussy about its food. It reproduces easily in captivity. 

Mates in caves

At mating time, this fish looks for a cave. If it doesn’t find an existing one, it can dig one in the lakebed or riverbed. There the fish mate and the eggs are laid.

After the eggs are laid, both the female and male help to guard the eggs and keep their surroundings clean until they hatch. After the larvae hatch, they stay close to their parents, who feed them and protect them against predators. After about three to four weeks, the juvenile fish are ready to look after themselves without their parents.

Kribensis thrives best in lakes or slowly flowing rivers or streams with lots of vegetation on the bottom.
