ok i got a 125 with 2 emp 400's and a canister soon.......so so far its a green terror....prolly gonna trade my uro for a real red terror.... so i was also thinkin about a jack and a oscar, so a gt and a rt and a jack and a oscar and a pleco or some sort of cat like a lace or somthing......you think thats to much ? compatability issues? i think ill have enough filtration......id like to put more maybe that would kinda curb the aggression from the rt.......i know the rt is aggressive but so is a gt and jack...so i thought maybe they would be evenly matched....??
