Who is the baddest america cichlid i would say dovi but im tryin to see what everyone thinks
I once had a mixed cichlid community tank with a pair of large 12" oscars that ruled a tank with seven slightly smaller Central Americans. One Parachromis loisellei, one P. dovii. one Kronoheros umbriferus all about ten inches each. This included a a common red devil, Two Mayan cichlids and a Herichthys carpintis. all four 8 inches each.
During that winter, the power went out at my house without me knowing. The oscars were dead in the morning. After that, the Red Devil took advantage of the other fishes weakened state and went on a rampage killing all three of the larger fish without even a scratch on him. The only fish he left alone were my Pearl scale cichlid and two Mayans all about 8 inches long. Parachromis loisellei,Parachromis dovii and the Umbee all have reputations for being dominating fish.I have read the same in practically every cichlid book I own, these fish are described as being very aggressive.
I ended up moving him to a separate tank in a area I would separate fish that were too aggressive and I still wanted to keep.
I placed a male Nosferatu labridens in the tank next to the Red Devil. The Nosfaratu was also around 8 inches long and he had outlasted his welcome in community tank I placed him after he killed his female during spawning.
These two fish would threaten each other through the galss day and day out. One day I came home to find the Nosferau jumped out of his and into the Red Devil tank, where he found out the hard way what RD's are capable of (Yes yes.No covers were on their tanks).
Well, I guess if you look at it from rock, paper, scissors perspective, I guess my answer would be common Amphilophus. dovii and Umbess are large predators. In my experience, predatory fish tend to be more reserved with equally sized fish, ignoring most fish they cannot swallow in onegulp
