Thanks for the quick response, I don't know what I would do without MAAST.

I think I will use a 20 gallon, as you suggested. I have one with a matching stand, sadly it is already occupied. I may move the fish in it now.

If I use a 20 gallon, I will be using a T-5 fixture that is 24 inches long with 2 bulbs.

Thanks again, all comments are greatly apreciated.
