i have a bunch of little dudes on the glass and on some of my LR. they look like little "@"'s. they need to be scraped off and they are kinda tuff to get off. the tank has been running about 4 months now. i got about 35 lbs of rock, about 20 of it was LR from LFS. what are these and will they become an issue?
