Emerald Crabs are NOT Reef safe!

[Diznaster]

nah, just noticed this today.. kinda hoping she was just going after something on the tree? wishful thinking..

my tank is mostly clean, but if she was going to be a coral eater, how about the endless amount of ugly trash zoas i have on my live rock!!!!!!!!!!!!!!!!!!!!!!!! i'd pay to find a fish that just annihilates zoas like they're going out of business

Funny that's exactly what I thought at first, oh your just cleaning a spot from the coral. The I saw it there the next few nights and realized all the missing flesh.

I've got 2 smaller ones (no idea if they're a male or female) but they stick to the algae

I think that since there's so much food for only two crabs, mine have never touched coral or fish

How's this working so far? Still A-OK?

Sorry to necro the thread!

Has anyone had an emerald eat frogspawn? My frogspawn is suddenly closed up and two heads look picked on. I added the emerald, two blue-legged hermits, and a chaeto refugium on Sunday. I noticed the start of the problem Tuesday morning. It's gotten worse. I haven't seen the emerald or the hermits bothering the frogspawn, but I can't watch all the time.

Cheers,

Emerald crabs are not to be trusted and ive seen them not eat them but pull the polyps off for no good reason.

Great. Thanks for the info.

I'm now thinking the problem is something worse. Will make a separate thread for it. j

I was watching my tank and saw my emerald just picking and eating tentacles off of mu torch so I bet this could have happened. Once I saw this he was banished to the sump where he lives now.

These and Peppermint shrimp are not to be trusted

Um, not that you want the coral damaged even more, but in the future, what about putting the favorite coral in the trap instead?

Your a genius. I would call that thinking outside the trap. At any rate the whole clean up crew thing is debatable IMO and no longer have anything but snails. The reality is the human keeping the reef tank is the cleanup crew and preventive maintenance is best.
