Well my main goal is to successfully house a trimac with a buttikoferi in a large tank where they can coexist was thinking 125gallon but now thinking 180gallon but if tested and these two were to go at it. Which do u think would take the cake on being tank boss also will throw in other fish to split aggression such as other cichlids like convicts, a pike or two, a catfish or two, a tiretrack eel, maybe a school of tinfoil barbs and lots of plants and caves and logs and rocks and driftwood for territories and breakup of lines of site and such was even thinking if worst came to worst throwing in a midas or red devil in there to breakup direct rivalry between the butti and trimac but who knows tell me what u guys think
