I have living proof in my room. My brother gave me one of his piranhas and i'm keeping it in a 20 gallon and it is perfectly healthy. I'm just sick of people always suggesting ridiculusly sized aquariums for just one fish.
50g is NOT to small for ONE 8" piranha. My brother raised 6 baby piranhas in a 10 gallon aquarium, and then moved them into a 35 gallon tall when they were all 8 inches long and they were all perfectly healthy. None of them were skittish or anything like that. The rule of thumb is that one inch...
I have one 8" red belly pirahna in a 50 gallon aquarium and i want to add more piranhas into the tank but I'm to cheap to buy adults. My question is, if i throw some juveniles in there (2-4") will the well fed adult devour them?
Thanks
