Ok! So after battling keeping my tang alive, i decided to start a QT set up! Mike, I'm still skeptical about keeping it out of my tank due to adding inverts/chaeto etc, but it's worth a shot! Gonna upgrade to a 125g or so in the spring! Corals need room to grow!lol! When I do, I'll use this tank to treat the fish to rid them of ich, and hopefully keep it out of my DT! Unfortunately my tang lost his appetite and I have him in a hospital tank with meds now! He has a bump on his eye! BTW, my hospital tank is 14 gallon rubbermaid container with a heater and airstone! I'm looking for a 20 gallon for the future but figure this will work!
