I have a 55 gallon tank with guppies, blood eyed tetras, danios, 2 yo-yo loaches, a school of neons, and one red wag platy. I was wondering what else I can feed my fish besides tetra color tropical flakes? I want a nice and health tank. Also, what can I feed guppy fry? As a future reference, what can I feed Clown loaches, ottos, snails, and plecos?
