A Haplochromis sp #44 hybrid?
An unidentified male cichlid from Lake Victoria. When I purchased this fish he looked to be the dominant male Astatotilapia nubila. I placed him in a 40 gallon grow out tank where he was not the dominant fish at all. He imediately lost all the black and pretty much looked like the picture below. He was very aggressive toward the two female nubila and killed them both in less than six months.
Unfortunately the Hap 44's hybridize so easily that I'm afraid he is likely a hybrid Hap 44 and nubilus.
