I purchased this fish labeled as Labidochromis caeruleus (yellow one above the heater).

I'm guessing it's a hybrid. Probably between a Metriaclima estherae and a Labidochromis caerleus is my guess.

It's a good looking fish but I think it will be removed from this tank.

Check teeth with a magnifier if needed. Look for the following.

L. caeruleus has unicuspid teeth in the wild.
Metriaclima has bicuspid teeth in the wild.
All cichlids continuous replace their teeth.
It has been shown that in captivity, cichlid dentation may change depending upon diet.
Recently, new species have been added to Labidochromis that have bicuspid teeth in the outer row.

The point of magnifier is to see if the all yellowfish dentation matches that of known L. caeruleus.
If all teeth are unicuspid in both Labidochromis, then all yellow fish is most likely Labidochromis.

Also check a Metriaclima dentation. They should be all bicuspid.
Compare yellow fish. If there are bicuspid fish in any rows, then the yellow fish is not likely Labidochromis.
Like a complete unknown
