Quite honestly I think it is better to do research about fish before purchasing, if you don't know what their diet is, then why purchase. But seeing they are one of my favorite fish, they are a carnivore, they like brineshrimp, mysis shrimp, bloodworms, basically any type of protein. My bigger ones eat freeze dried plankton mysis and krill.

wow beautiful.. i feed my calvus brine shrimp and mytsis shrimp and flake food ..

there also love eating any other fishes eggs and all live foods

Tang O,
I did do alot of research on my calvus before I got a pair. I was asking because currently they are eating high quality cichlid flakes, nini cichlid pellets, brine shrimp, and blood worms. And I wanted to know what else they would like to eat.

well then you should have refined the question a little bit. Watch out if you have any other breeding pairs in the tank (of any species) cause they are oportunistic preditors

Great fish.

Thanks Tang O.
