green terror tank mate suggestions

i had to move my gt to my 55gallon tank and hes currently alone.......its got 2 emp 400's on it and a powerhead.....so im wondering what i might be able to put in it... its got a nice turnover rate now so it should be able to handle a few more fish in it

Yeah i had a jack dempsey before i was thinkin about getting anouther one...it would have to be a larger one tho.......but id have to add more fish so maybe they wouldnt fight....my gt **** near killed a oscar i put in the tank when i had them in my 125 .....i had a fake rt in their with him for over a year but i guess the xfer did him in when i had to move he looked a lil rough the gt always picked on him......i would like ot have a real red terror and i thought about anouther gt but i woundnt wanna deal with the babies if they mated but yah thats not a bad suggestion keep in mind tho the gt i've had for like 2 years and hes like 4-5 inchs long....and mean right now he likes to pick fights with his reflection and attack the intake on the emps and the clay pot caves....lol im gonna build up some caves and such ...larger ones for them to claim
