Well I tried my best w the pics; they don't stay still for long...Maybe these will help w the id. Like I said previously, I am no expert and don't even know if they are even Metynnis Maculatus. I thought the pics were close and went with it. Thanks for the help
a clearer pic of the mouth area will let us know if they are piranhas or not an overbite is alwasy a pacu no overbite nor underbite is a silver dollar or pacu and an underbite is a piranha
edit: you stated you saw some teeth on them and they had an underbite correct ? in that case i stand by the fact that there just RBP's they look identical to mine (yes i finaly got some pics up later guys)
Def saw teeth; not so sure about any underbite though. I will have to look closer and try to get some better pics. Thanks for the feedback! I have two fairly large pacus and the mouths are not the same, plus if I remember correctly I dont recall seeing any teeth at all when they were juvies! They sure eat me out of house and home now though!
yeah i aggree they have a striking resemblance to pacu but i cant say for sure the mouth looks more pacus-like but the body looks just like any piranha (pacus if i recall are more rounded)
