Just didn't seem like a polite way of putting your suggestion to me either , kind of condescending , just the feeling I got .
Oh basically the fish in question are mine as well , and thanks everyone for your concern , we will be changing to sand , because that is what my Son wants .
Most of the fish are back in the tank now, but I'm letting the African butterfly and mogurnda stay in the temporary tank for a while, both seem to like it better
I'll try to get a few pics up, it looks pretty nice now
