Needs to be in his own tank or in a a very large community tank. I had him in a 135-gal and he tried to take out the Oscar and Vieja.
I then tried him in a 75 gallon with (2) 9 year old silver dollars and a sun catfish (8-9") that were also in the 135-gal. He never paid any attention to them in the 135 but i guess the 75 was just too small for him to share with any other fish. I've had him in a 20-gal for over 2 weeks now so i've given up on trying to sell him. Now, i'm just looking for the fist person with an adequate tank who's willing to pick him up. Also, if anyone knows where i could donate him in the Bakersfield area i'd appreciate some info. Thanks
