I also wasn't aware that pacu had a double row of teeth. Learn something everyday!! But I always looked toward the lips, jaw region from differentiation. But I've kept them both regularly so it's easy for me to tell at a glance but this is a great thread and informative.
Identify Red Bellied Pacu from a Red Bellied Piranha
- Thread starter HiGhTiMeZ
- Start date
those pics really helped me realize that the pet store sold me one red-belly piranha and 2 red belly pacu (note to self dont buy from Petsmart idiots)... I kept wondering why 2 of them looked more alike and are growing so quick, they are also more aggressive ... The littler one (the piranha) is more docile and is also darker than the other two and has not grown much since i bought him 4 months ago.
that is a good pic of what you are talking about they are curved and stuff the pacus are flat that makes a lot of sense
the people at petsmart dont know there but from the ground becuz they ask you how mean fish are in a tank and then they tell you if you can buy that fish or not and they do not know what to put them into.SuperToad520;3019548; said:

I don't think these two questions should belong in this topic. next time try to post them in general piranha disucss section.peter the graetfish;3068886; said:
The answer to your question is NO.
Black piranha is a solo species and should be keep in a tank all by itself.
only pygo (rbps, caribes and piraya) can be kept in a shoal.
