We kept Mayan cichlids years ago, there good cichlids. Aggressive and fun to keep. In fact I bought one awhile back from our lfs, it was tiny as it turned out it’s not a Mayan at all but an orange saum. We bought 3 or 4 bags of cichlids with several in each. He probably just scooped up the wrong one. I’m planning on ordering a few that way I know I get one. We’ve kept actual Red Terrors Festae as well. They look similar but act much different. Mayan cichlids in my experience are more aggressive then festae. Both are awesome, Red terror’s look better especially the female’s
