this tank would look awesome with a small group of uaru or satanoperca. i hope it worked out, usually my cichlids lip lock every couple months to update the hierarchy. sometimes one will have become stronger than the other or starts to think its become stronger but once the fight is sorted out theyll ignore eachother for a couple months. these types of wounds have healed in less than a day for me i add stressguard when i notice wounds so im not sure if that heals them or if its just the fish themselves .
