Is it okay to feed my comet goldfish tropical fish flake food?
Yes it is, BUT you must look for a food with out corn in it. Usually tropical fish food is better quality than many goldfish foods available. A good food is hard to find. You want plenty of seafood like whole fish meal, and krill, and some spirolina in it too. You want protien about 30% and fat around 10%. Look for that and don’t worry about if its tropical or goldfish food. Corn indicated the food is full of cheap filler and is low quality. Also named as corn guten meal, or gluten meal. Avoid corn it causes digestive problems and floating.
