Weird my Ps wont really take the floating ones right now. They take sinking ones. i tried large omega floating and ciclid gold floating but they wont take them. I dont know its too big for them or too hard to bite. I do plan on having them take all kinds of pellets and veggiesI feed them Hikari Jumbo carnisticks, that I get from Amazon. They were about 2 1/2" when they got on them, I used to break them in half for them. I tried the sinking ones, but they'd never touch them.
