Before I moved the tank, I was battling a red hair algae problem and had been waiting to restock/diversify my cleaning crew until I moved. Since then, I got the 5 emeralds, 20 ceriths and all the scarlets, plus moved all the blue leggeds devils. The algae is doing better, although I don't know how much is due to a total housecleaning plus scraping some off during the move. I want to have enough numbers and diversity in a crew to keep the reef stable and prevent the algae problems. I just wasn't sure if I'm currently there.
I haven't seen too many people advocate the sand sifting stars on this board due to wiping out the sand bed.
Sammy, when you said you'd like to see more diversity, what did you have in mind?
btw, I forgot to mention that I also have 1 blue tuxedo urchin (who I witnessed pooping for the first time yesterday - very odd)!
