EMERALD CRABS

[JDSmith]

Should I take a chance and try an Emerald Crab in my tank to attempt to get control of Bubble Algae, or is this just asking for trouble for my coral and snails?

i have heard as they get bigger they can get aggressive, but havent experienced it in the past.

i have two of them in my biocube and the are extremely UNagressive. they just hang out and eat algea all day.

It really depends on the crab, some develop a taste for xenia, candy cane, or just about any other coral. Some won't even touch bubble algae where others eat it like mad. It may be an idea to give it a shot but be prepared to snatch it up should your corals start to show signs of snackage.
