David,
No one bites out here, ask your question or tell us about your fish and the types of tanks you have. It would be nice to know what others do.
My husband is a home hobbist that breeds angel fish. Sometimes he has too many that is for sure, but it keeps him busy and gives us something to talk about together. He is currently breeding black comtail veils and two different types of Koi's. He has 3 55's, 1 50 high, 3 40's, 1 20, 2 10's and 3 5's and most of the time there are plenty of fish in all of them.
What do you do?
Karen and Jimmy
