My Black piranha

[elk]

I purchased this beautiful rhom about a month ago from Bigals east and let me tell you,he is the most socialable piranha I ever had.
Unlike the reds I had a few years back that were always hiding,very skittish and woud only eat when no one around.
My black is always swimming around,when I approach the tank,he comes right to the glass and stares at me and the best is when its feeding time.I throw in krill or shrimp and he devours it in seconds with lights on and me in front.
Just dont try and put any kind of pleco in with him or it will be killed.
Blacks are extremely a killing machine.
