I just got 80 dollars for my birthday and I figured I'm going to get decorations for my goldfish tank (its completely empty except for gravel) And food for all the fish. Anyway I was wondering what I should get as far as food for my bettas. I don't want to have to deal with anything live or somthing that will go bad soon. I just want things that come prepackaged and last as long as pellets. Is there anything I can get like that besides the pellets?
