I would love to know what size tank you have him in?
Our stick your finger in it's mouth, if it comes out mangled it is a pacu, if it doesn't come back out at all it is a redbelly. send picspiranha45 said:so young black pacus have red-tipped fins, and that's the easiest way to differentiate them from redbellies?
