hi, just wondering about possible tankmates for my new 6" male spangled pike cichlid. he's in a 130g tank with lots of driftwood, fake plants, rock caves.. he's kind of on the aggressive/dominant side.. but i want a few more fish in there, since there is not a lot of action in the tank right now. i want something nice lookin and colorful, that may help to bring the pike out more too.. any suggestions would be great! thx.
