wow, i dont think id want to do that to myself personally lol, but i love rays so what am i gonna do. i just wont stick my hand in to pet them is all. same as i was gonna do for the piranha tank.
pacu is one of those fish that if they get to know the owner, will kind of be personable like an oscar actually. pacu have lots of rows of small teeth. piranha, you dont pet those....
