I saw something the other day that would be good for hiding the babies from the other fish. The frame was like a half-sphere shaped plastic mesh thing, kinda like the kind of thing they make the one-quart strawberry baskets out of. Can you visualise that, or am I just being perplexing again? lol.
Anyway, the mesh was covered all over in little plastic clover leaves, leaving just little tiny spaces between all the leaves. Baby fish could easily fit in, but no adult fish would be able to. Also, part of one side had been flattened, so you could place it right against the tank wall and see inside without leaving a huge gap for hungry adult fish. It was roughly the size of a softball cut in half.
Does anyone know what those things are called? I think they're really neat. >_> And they might be what the topic creator needs.
