Sorry Im no help to you, but I have a similar question and was wondering if you could help. I had a recent out break of ick in my tank. My yellow tang has it the worst. Ive had him for over 9 months and hes always been happy and healthy. I did a water change and got a new clown fish within a day of eachother. Im not sure which one brought it on the ick but now all 3 fish I have it. My Yellow Tang, new Clown (not sure which kind, im a newbie) and my diamond goby. My only other fish is a damsel and it does not show any signs but Im going to QT him just in case. Besides my Tang and Damsel are close and like to school together, the new clown is starting to join in.
Question 1: I am setting up my QT tank right now, but I wasnt sure if I should put a little bit of sand in there for my goby?? He loves the sand and spends all day sifting around, but most threads online say to leave it empty besides a few pieces of PVC.
Question 2: I read the entire thread and the main debate was about your tang, and the size thank it was in. Is my 28 gallon tank to small for my Yellow Tang?? Hes always seemed to be a very happy, social, and a heathy fish. Besides my goby which stays under rocks a lot, a tiny blue damsel (less than 1 inch) , and the new tiny clown I got which is also less an 1 inch, my Yellow Tang has the rest of the tank to himself, and I dont plan on getting any more fish just a few more corals. Do you think that I am stressing him out by keeping him in my tank? Besides the damsel that I have had since day one of my tank, my Yellow Tang is my second oldest fish and Ive grown rather attached. Should I risk taking him back to the fish store for something smaller, in hopes he finds a new bigger home?
