IM BACK...and as usual...I have a question. Ok, i've had my 55 gal up for about....a year now. I have 2 perc clowns, a watchman goby, cleaner shrimp, and coral banded, along with snails and small feather dusters. In my refugium, there are little fuzzy worms. They primarily come out at night, they are about 1/8" and they have a hint of blue in them i think. I haven't had any livestock added to my tank since I left for the marines about 10 months ago. They haven't harmed anything that i've noticed but I'm still alittle worried. I will try to include some pictures when I have time, maybe tommorrow if i have time.
