I just wanted to share that I traded in my Barbs a couple days ago and now I have two Rainbow Sharks and a Rainbow Gourami. They are absolutley beautiful to watch, especially the sharks, which I purchased them at about 3 inches long each. I've got three different caves in my tank at the moment and the sharks have already set up camp in two of them. The Gourami hangs out all over the place and sometimes in the third cave in which he gets a visit sometimes by the sharks and they seem just fine together. I'm planning on adding more Gouramis, a few more sharks, and Angel Fish to the mix in the future. It's fun to sit here in my office and just stare at them. I was a little bummed to get rid of the Tiger Barbs since they were my first fish but I wanted to go a different direction. Thanks to everyone on here who are always more than happy to answer even the most mundane of questions.
