I have a red devil, jack dempsey, convict, pleco and bichir in my tank... they all get along fairly fine with no horrible issues... I added a fish I bought on a whim (bad idea) a columbian pike... last one in the fishstore, listed him as a cichlid, had no clue what variety or any other info about him he doesn't seem aggressive and usually hides during the day, but he isn't being bullied, just his preference... so... any info about these columbian pikes? A google search turned up relatively useless...it's in a 90 gallon.
