I have I guess what would be considered a semi aggressive tank. I have 7 tiger barbs, a rainbow shark and 2 flying foxes. I also have 2 neon tetras that were carry overs from a tank a year or 2 ago. I wasn't planning on getting anymore seeing I didn't know how they would work with the barbs. They seem to be fine except they don't really do much because 2 aren't enough to school with. If I would go buy about 7 more or so would that be a bad idea? I want the others to have friends but if the barbs will just attack them its not really worth it. What does everyone think I should do?
