Ok, so this morning I went to my tank to say "good morning" to my 3 chromis (1 still missing) and chocolate chip star. I found on top of one of my rocks some brownish 'hair' growing on it, it was about 1/2 to 1 inch long. What is this? I can take a pic and post it if needed. But it just looks like fine hair, say a cotton ball spread out thinly and brownish. This thing was not there last night!! I was enjoying looking at my tank last night and it wasn't there! Everybody is doing ok, I haven't tested the H2O this week (going to). The tank is 1 month old and had been cycled since pretty much week 2. I'm thinking is my 1st algae bloom and it will clear. I just brushed the hair off with a toothbrush and see what happens. Sorry for the long post... :?
