How big will this guy get?

[bcavalli]

So I've had several Emerald Crabs for over a year. Several are getting pretty large and one of them (obviously a male) is getting pretty dang big. His shell is about the size of a 1/2 dollar. And I would estimate his claw to claw span is at least 6". I haven't had any issues with him or any of the others picking at any corals (yet).

But, how big will he eventually get? Will I need to worry about him attacking sleeping fish or eventually turning on my corals? Thanks in advance for any opinions!

He is a crab and will opportunisticly feed on any fish given the proper situation , but I haven't ever had issues with my mithril crabs but I try to only keep the smaller ones adolescent or female because they seem less aggressive than the large one's

Sounds like I may want to move him to the fuge before something happens. Thanks for the info!

I recommend a pot of boiling water and some melted butter.

Maybe I should wait a couple more months before I eat him. Then I can get two bites instead of one. Lol

Yea I watched mine hang from a piece of rock and clamp my shrimp didn't eat it just cut it half

I had a feeling I should have grabbed him and thrown him in the sump when I had the chance.

I have had numerous emerald/mithrax crabs over the years in various tanks and only had an issue with one. I bought a big one cause hey, he could eat a lot of bubble algae, right? I was wrong. Way wrong. He had a den and would grab any and all CUC for a quick meal. Supposedly big males become even more opportunistic in their diet. Took a while to catch him. Then he became trigger food at my lfs. Good stuff!

Call Sig Hansen to come and get him out of your tank

They grow for their whole lives so, how big he gets depends on how long he lives.

Some of them are more aggressive than others, but if you are concerned, you're probably better sumping him. Then he can live out his days and not harm your stuff.

Thanks for the great advice as always Jenn! In the sump he goes.
