Ok so heres my story, I started keeping fish a few months ago and love it since then I have upgraded from a 10 gallon tank to a 55g tank heavily planted with co2 injections. so far i have 6 roseline sharks, 7 tiger barbs, and a rainbow shark. They all get along perfectly and the roseline and tiger barbs even school together most of the time. The rainbow shark can get a bit nippy during feeding time but he is mostly peaceful. I also have been able to keep 8ish amano shrimp that are doing fine in the tank. Despite what people say about how hard it is to keep roseline in a warmer co2 injected tank the roseline are doing fine and I was wondering If I would be able to add 5-6 odessa barbs to the mix. I now I might be overstocking the tank but it is well planted and a lot of water flow form power heads. Any advice would be nice, I saw the odessa in the store the other day and I think they would look perfect in my tank!
