I have a Fluval Flex 32.5 planted tank. My wife and son are challenging me to stock it with the MOST colourful freshwater fish possible lol. We want it to be peaceful so want to stick with Tetras, Rasboras and peaceful Barb's. No livebearers and no Glo Fish please. What species would you suggest for bottom dwellers, mid level and upper level inhabitants? I'm trying to think outside the box and steer away from the usual suspects but it's not easy. Looking forward to hearing your suggestions.
