Red bellied Piranha- Pygocentrus nattereri It’s been a while since we’ve had a group of Red Bellied Piranha like these. Size approximately 8” The silver glitter effect contrasts so beautifully with the intense red to create a stunning sight! These guys would be best sold as a group, certainly no less than 3 to truly appreciate them. P. nattereri are a gregarious species (live in groups)keeping just one in a tank takes away what they’re all about imo. If that’s the plan then checkout the Serrasal
