I have a sunburst (i.e. Honey) dwarf gourami and I am suspecting that he may not like the food I have offered him. I tried the below food and it seems that he tries to eat it but then spits it back out: 1. Tropical Flake Fish Food by Omega One 2. Bloodworms 3. Omega One pellets 4. New Life Spectrum small pellet food What gives? Is this normal eating behavior? Thanks.
