The fish is in a 30 gal qt tank w/ some frags,clam,hermits and snails and LR. I treated the tank with no sick fish`s ick med. www.nosickfish.com I just followed their directions and fed w/garlic on the food. Good luck with the treatment. I heard from someone that the med works better in a small tank. The other fish I had in there were a percula,5 cromis and a yellow tail damsel.Non of the other fish got sick or were affected by the med. Tim
