well ive got a 125g that im currently trying to re-arrange the inhabitants of.. i have a rtc and a tsn that i was planning on sticking into a pond thats in my backyard once they outgrew it but its more of a natural pond and once they go in ill never see then again.. so rather then grow them out to loose them if i can find someone who will enjoy them then great but once i find suitable homes for the two, or if i cant ill just wait it out, but ill probably look into one of these, which would you guys prefer for a 125? its either going to be a nice zen peaceful calm tank or in going to stock it full of piranhas.. any opinions on what would be more interesting? the catfish are kinda boring, all they do is hide all day and come out to eat only if its dark.. and im loosing inhabitants by the day but if i ended up with some red bellies id probably just put some driftwood so they could hide but it wouldn't be real comfortable for them to do so, maybe some manzanita. and i realize they aren't the killing machines they've been made out to be but that not really what im looking for
