It sounds good to me, though I don't know much about angels... I think Yoyos may eventually need a bigger tank, but you're looking at more than a year until then. We have some in a 40 gallon (and have for over a year now) and none of them are fully grown yet. The biggest one is not quite four inches and has pretty reticulation forming .
