I have 2 Tiger Barbs, 1 leporinus fasciatus, 1 blackfin shark, and a plesectimus. Everything looks like its going well. I have fed the fish flakes and all of them ate. The leporinus fasciatus is hiding in a cave after eating. Tiger Barbs showing a little aggresion but nothing serious. Soon I am upgrading to a 30 gallon tank. Any suggestions? Does everything sound alright? Thanks!
