PurpleTang has Ich

Thanks for all the ideas; In fact I got a Fire shrimp that immediately opened for business and the Tang swam right over; The ich comes and goes every other day;;;the temp fluctuates about 2 degrees...78/80; it seems as though when the lights are off longer that the Ich not as pronounced; he gave it to my Dotty back who fought it off and is fine; i hate to keep medicating, so ill try the above first


thanks again
