OK.. Here's a RTC at my lfs shoved in a lil bowfront aquarium, fish measures about 22", he came out of a 60 gallon tank that the owner said he was "growing out of", he's been in the store about a month and i'm tired of seeing him in the lil tank all crammed up not even able to turn around and touching front and back, owner said if i want he's mine to take because the can't get rid of him and no where to put him, only problem is the biggest tank i have spare right now is a 150gal and it'll be may before i can even think about completing a 1000+ gallon aquarium for him. Any opinions or ideas?
