I recently picked up a new venustus cichlid and I am having a hard time getting him to eat. He will take Hikari cichlid pellets but then spits them out. He also goes to the bottom and does the same with sinking carnivore. Any suggestions or reason why he does that? There are feeders in there as well. I am going to try frozen bloodworms and Mysis shrimp tomorrow if he continues to not eat.
