Hello Guyb93, I have the in a 150 gallon. They are huge!! My guess is an estimate, but I they are close to 2ft long. They are beautiful and I love them but if I dont find a remedy soon I'll be forced to give one of them away.
I'm having issues with my pacu. I have two large Pacu's for 11 years. I raised them. One has become really aggressive to the other by attacking him and biting his flesh. What can I do?
