So since my 4-6" filament barbs were all unfortunately wiped out and I was on Long Island I decided to visit aqua hut to pick up a new schooling fish. I wanted something slightly smaller, but still tightly schooling. I was considering dwarf rainbows, but then I saw the Exodons aka bucktooth tetra. I bought 10 between 1"-2". Then I came on here. I know they're aggressive, but most people here seem to think they will kill all fish and are monsters. I wanted to know if anyone had personal experience. I have a 7-8" green terror, a 6" red severum, a 4" bristlenose pleco and a 6" blood parrot currently in the tank. I spoke with a staff member in aqua hut who I trust and have been friends with and trust since 2006. He knows my fish and doesn't think they will be a problem. I was hoping you guys could let me know if he's wrong and if I'm in trouble here. It's a 55 gallon that's planted, I have a rena xp3 and an aquaclear 110 on the tank and I do two 25% water changes per week. Thanks guys!
