How long does it take for african cichlids to mature on average?

Any aggressive cichlids that can take down a flowerhorn, 10 points. No oscar or any fish that grows to 18 inch

• Answer:

  Jack Dempsey, Green Terror, almost any of the Cynotilapia's probably. Given you asked a similar question about aggressive and territorial and hardy cichlids, I'm curious to what you are thinking actually. Just because you have an aggressive or mean tempered cichlid of any lake of origin, doesn't mean it's a good fish to keep actually. I personally think flowerhorns are ugly and hideous. I find significantly more pleasure and joy keeping and breeding my Africans even if they don't attain the same size, aggressiveness or temperment as a flowerhorn. I've got to say watching my male Nimbochromis Venustus take on an albino channel cat that's about double his length if it wanders into his area is a sight to see.
