Thanks Dogstar. Are those a type of Nudibranch? I've read that "lettuce leaf" (common name) nudis will eat hair algae. I think my problem started when a powerhead fell off the tank wall and stirred my DSB. :scared: And, no. (shame on me) I havn't checked my nitrates. I had just checked them before this happened and they were next to nothing on the scale(0 trites and 0 amonia). I'm going to do a water change, then recheck.
I was thinking of replacing some of my cleaner crew from SWF.com. I ordered a crew last April and they are needing some reinforcements. I think it is natural for them to dwindle, is it not?
