I have a 15 gallon homebuilt tank...that has run for about 2 months with a single betta, recently I have added a plecos...and apple snail... The betta contracted ich shortly after adding the other fish, was treated using coppersafe at recommended dosages, shortly after treatment the initial "sand" grains are gone but betta is very lathargic and slow. White patches have begun to appear on the sides of the tank in several spots throughout the tank....the best discription after looking through a *30 handheld micro. would be: small almost bubble like structure when viewed through the glass but an almost 3d fuzz on the inside of tank. Any ideas what I have got in the tank, or links to possible info would be greatly app.
