Hello everyone, currently I have 3 siamese algae eaters, 4 neon tetras,3 glowlight danios,3 zebra danios, 2 tri colour sharks, 2 red tail sharks.... I'm thinking of adding dwarf cichlids to the mix or tiger barbs, the tank is 90 gallons, lots of good rock cover and shortly ill be adding line plants, which should I add? Or can I add both? I worry about tiger barbs nipping fins but I hear in larger schools they're ok? What would you add? Thanks!
