I am waiting for my 6 RB piranha in an 80 gallon to start ripping at eachother as they get cramped. I thought one or two would die before they reached this size( 4 inches) but no dice there. anybody have experience selling fish to local pet stores? i know piranha are usually a hot sale at these places and they have trouble keeping them stocked. The place I'm thinking of sells gaunt one inch RB's for 20 bucks. I really don't want to have to let them kill eachother or set up another tank. i think this would be the best option. so yeah, do these type of deals occur, and if so, what do you think I could ask price wise for a four incher? I think they may be super reds, still very silver and red at this size. Thanks
