I got a fish for a gift.
At the LFS where it was bought they sold it as a Jack Dempsey.
My friends thought it was a bargain price for such a "big Jack Dempsey cichlid". They informed me that he is about 10cm, which is totally acceptable for the size fish I already have versus a Jack Dempsey temperament.
When my friends brought me the"Jack Dempsey" gift, I got a big surprise.
It was not a 10cm Jack Dempsey, but rather a fully grown 20cm Texas cichlid.
He is the most agressive fish I have ever seen. A real Terror. The other fish are surviving but he wants to, no sorry he will be king of the tank. He is together with Oscars, Arowana and Severum's.
Its a beautiful cichlid, but a problem child.
I'll probably have to move him to his own tank at some stage, still monitoring the situation. Cannot tell my friends I returned their gift.
