Origin and description

The Cobalt blue zebra cichlid is endemic to Lake Malawi in Africa. They are mostly found among sandy or rocky bottoms of the lake, where they feed on zooplankton and algae.

Their bodies are a light blue color. This fish is a hardy species, but it’s best to keep them in an aquarium with other non-aggressive fish of similar size.

Breeding

Cobalt blue zebra cichlid

It is recommended that three females be kept in the tank for every one male to increase the chances of breeding. The duller color of female fish can be used to identify them. The eggs of a cobalt blue zebra cichlid female are laid on a rock before being scooped into her during spawning.

The female then swims behind the male as he fertilizes her eggs. Immediately after fertilization, it is best to separate the female from the male. The eggs hatch within three weeks, after fertilization, and the cobalt blue zebra cichlid juvenile can be fed with brine shrimp nauplii.

Are they aggressive or peaceful?

The cobalt blue cichlid is one of the more aggressive fish of the family, adapting well to other aggressive fish. Do not place peaceful fish with them.

The average lifespan for this species is about five years, although they can live longer than that, up to 10 years, when cared for properly.

Parasites and diseases

In aquariums, the most common parasite of the cobalt blue zebra cichlid is ichthyophthirius multifiliis. This parasite causes white spots on the skin which are commonly mistaken for fungus.

Other diseases include bacterial infections like ulcerative and fin rot and parasitic infections like anchor worms and protozoan infections like Hexamita.

To prevent these from occurring in an aquarium or pond with this fish, provide a healthy environment with good filtration and water quality by performing regular water changes. These fish also need to be fed fresh foods rich in protein and vitamin B-12 since they cannot produce their own vitamin B-12 due to a lack of intestinal bacteria.

Predators (What animals prey on them)

Their predators are African cichlids, tiger fish, and piranhas. A few ways to prevent them from being eaten by these predators is to keep an eye on the tank at all times and make sure that there is no way for other fish to get in.
