what to feed?


ive got a sailfin and one spot foxface that both have HLLE. it seems to be getting better since i started dosing calcium but its still there....the sailfins top fin is almost totally back from being totally gone but there are still pits on both of their faces and the foxfaces tail fin is very small...
im assuming nutrition is the issue. they get seaweed and meaty foods. is there anything else? they are the only fish in the tank with it...
ive got vitamin c on the way should be here tomorrow.
