Hey all, I have a 20 gallon tank with a firefish, maroon clown, cleaner shrimp, long tentacle anemone, and a royal gramma. I noticed the Gramma (the newest edition to the tank) has a few little dots that I suspect to be ich. I was wondering if a methylene blue dip would be beneficial? If so, how would I go about doing this? and how long should they be dipped for? - Thanks
