This was my parrot we had hoped was female, but ended up being an infertile male. He is happily living in a 125 with his girlfriend and they try to breed every now and again even. He was softball sized.
My larger female kkp (the queen) would tear my hand off if I gave her the opportunity. When she bites me she stays latched on and rips and twists. The most aggressive fish I've ever owned.
