thanks for all the advice. i'm going to try to arrange to get the 20 gallon today or tomorrow, as i had arranged a trade for it with a friend. if i can't, i'll look into the silicone, although i've never used the stuff and i don't know if i'd trust my first try on something like this. for now, i have all the fish in the 5 gallon and fingers crossed. being in an apartment i can't risk any flooding.
That is what life experience is all about. Do a little internet research on application, barrow a tube silicone from friend, and go for it. These learning experiences in life are priceless and make you more socially independent, and gives you the satisfaction of recycling something you can use for many things from full use to a terrarium to a QT IMHO.
