I have a blue neon dwarf gourami that I think is dying. He was in a 20 gal tank with two cory cat's, one red tail shark, and one paradise blue gourami. I am not sure who beat him up but he's not looking too good. Long story made short, the LFS said he would be fine in the 20 gal tank with the fish mentioned. He was wrong. I have since put him in a 5 gal tank and treating him with Melafin. Is there anything else I should be using as far as medication? His fins are crumpled and he is "dented" from the shark and/or the gourami. His color is gone where he is dented. He was hiding the last week but did manage to come out for food. I did notice that he did not eat that much last Saturday. Any and all advice is appreciated. T hanks in advance.
PS I feel so bad about this fish.
