Hey guys I was thinking of getting a red belly piranha for my 500L/132G tank. Is this fish as aggressive as people say? Google says you need min 400L/105G for 8 of them but I'm not sure if it's compatible with my fish. I got 2 big plecos, 1 baby royal Pleco and one medium sized pacu. Can I do it?8mo ⋅ GreekGamer05 ⋅ r/aquarium
