This might seem like a strange thing to ask, but is it ok to give my tropical and cold fish avocado. The reason I ask is I was doing a total clean of 1 of my tanks and some of the snails started eating a small piece of avocado that was in the sink.
Alot of people say to feed your fish some vegetable matter, are avocado's considered ok or should I stick to zucchini, also whats the best way of keeping the zucchini in the bottom to the tank?
