Steve,
Glad to hear you had such great success. Has anyone seen any emerald's around town? I'd like to get one in ASAP to start workin away on it. Although, I totally hate crabs, they creep me out so much.. ugly creatures.. but if they can remove all my BA.. then they're okay by me.
Rich,
I've heard mixed opinions on bubble algae breaking in the tank. Some say it won't cause more to spread, some say it will. I don't know what to believe! haha. The thing is the algae is pretty much on every rock , but in small amounts, some only one or two bubbles... and it's suuuuuch a PITA to remove from a 20g, I have no room for error... and lifting rocks will cause a detritus storm and i don't want to chance some kind of mini-cycle with all my SPS corals and clam, etc, etc....
You say emeralds may eat other things... like what? heh, I have a bunch of zoos and SPS corals and a clam, and a frogspawn.. that's it really.
I like cowfish a lot too, just can't keep one !
