Who has had good experience with these guys. I have had lots over the yrs and I have found them to be not worth the money, also not mention, my current emerald was just caught eating some copper colored zoo's. I have seen one destroy yellow polyps and button polyps before also. >:(.
Once I catch the one I have it will be the last one. :(
I have had two for 8 months that I got at AquaValley. Never any problems and never had them eat or pick at any corals. That being said, they are small and not full grown. When I had algae, they didn't consume very much of that, although I always saw them picking at it. I had a few bubble algaes that came with some live rock. That disappeared, so they may have done something with those as they are reported to eat bubble algae. However, I never saw them or anything else eat it.
My only problem with them is they are shy and only come out at night. Thus, I would like to see them more.
Wooki
little devils in my exp... ive had 4, none ever touched bubble algae and one would eat corals. Ususally SPS for me. get rid of it for sure.
Now to catch him I need a mantis on a string ;D.
He is very small about the size of a dime across his shell.
I have 3 emeralds in my tank, and love looking for them in the liverock and watching them scuttle around after food at feeding time. I don't keep any coral, so any tendency for them to nip and things is not a concern I have. :) They sure are good at finding hiding spots though!!!
