well for the past 3 days my two O's were fighting. one of the O's scales were coming off pretty badly and he started "sleeping" on his side. i got a little worried so i decided to buy a tank divider, but i came up a dead end. their was no divider for my tank size(which is a 40 gal) so i bought some plexi or flexi glass and drilled some holes into it and used some suction cups to put it in place. its pretty easy to do and becareful not to drill it too hard before the glass might crack. well i hope someone has found this useful...
