I have some gold fish flake food and no gold fish. The food is not very old, and I think it is perfectly good food. If I could I’d just give it to someone, but I do not know anyone near by who would need it. My question is; could I occasionally give a little of it to my tropical fish? It may still go bad before I use it up, but I’d rather use a little of it than waste it all. I know the two types of fish have different needs. I also know that some variety is good for fish. So... what do you think? What are the reasons I shouldn't feed the food to my tropical fish?
