Labidochromis caeruleus(Fryer 1956) the (yellow) blue cichlid

Labidochromis caeruleus - the black back cichlid - is probably one of the widest kept cichlids. Stunning in colouration it is found along a large part of the west coast of Lake Malawi. Although an mbuna, this fish is extremely passive and often kept in mixed communities.

But what is so remarkable is this cichlids has a variety of colour morphs, most of which are not yellow!  The clue is in the name as they are named caeruleus for their colour. Most morphs of this cichlid are in fact blue. Other combinations include white, blue white and yellow white. Indeed the famous yellow morph is only found in a small stretch of the lake near Lion's Cove and it is here from where our hobby fish originate. And most are descended from only one pair. This interbreeding has caused a huge deteriation in colour which is why many available are now washed out with excessive peppering. A far cry ftom their wild compatriates.

Sadly, due to overcollection and their small wild population, this fish should now be considered as vulnerable. Natural or human disaster could easily wipe out the beautiful yellow caeruleus. A few further collections have been made but the population density is becoming low so it may be time to introduce protective measures to save this fish. The pictures show my f1 specimens.
