Ok ive had two cichla for awhile now maybe 6 months or so. Just got back from florida brought two more cichla back that i ended up catching down in florida. Now my original two always got alone never had a issue with them. Now the two new larger cichla are in the tank . One of my original two has decided he wants to hang with the big boys. and keeps flairing up and chaseing his original tank mate.
