SO, I got this piranha as a gift, but my boyfriend isnt setting up his new tank for awhile. He has a large black piranha in a 120 gal and an unidentified little guy in a 20 gal (please excuse my terminology; Im new with the piranhas). I have him in a small 10gal, but I thought it was going to be a really temporary thing, like a holding place until I surprised him with it. It is clearly not going to work for much longer. He looks nervous and runs into the glass a lot. He seems aggressive. He is eating though.
I have a 55gal community tank of a large blood parrot and blue rams so I definitely cant put him in there.
Any suggestions how I might safely and quickly get a larger set up to transfer him without totally stressing him out?
No way I want to kill him. He cost me $150! Plus hes pretty cool.
