Hello. I'm having problems with my dwarf gourami. I've recently got him about a week ago, and I noticed that he's very picky with what he eats. I bought Tetramin's tropical flake food for his diet. This flake food has many different colors and for some reason my gourami only eats the red flakes. All the other flakes that he puts in his mouth, comes right back out, scattering bits of food all over. This means that i have to clean the tank more and such. Is there anything else I can feed him on a daily basis?
