how big is to big for an emerald crabs in a 75g
I have 2 emerald crabs in my 75g and they r pretty big IMO maybe 1"-1 1/8" I think that they may have taken out a turbo snail and they beat up on others at feeding time I'm begining to think that they were a bad idea but I'll never catch em in 120lbs of rock! Has anyone else had bad luck with them and how would I catch em?

A Mantis Shrimp would take care of them, or a large Trigger.
In full honesty though, try using a small glass to catch them. Just put some food inside of it near where they hang out. When the fall in, they wont get out.

I have 2 in a 90g and they (so far) haven't done anything but make a big dent in my algae problem. Other than occasionally pimp slapping a stray hermit off of their current feeding spot they haven't touched a thing. They don't even budge when food hits the tank. I guess being in a lush pile of algae outweighs leaving the spot for other food. I am sure now that I have remarked on their excellent behavior they will turn into terrors. Or they will run out of algae then I will see their true colors...
Anyway, most recommend taking a glass cup and placing it angled in the sand or against the rockwork and dropping some food he would find appealing into the cup. They climb in for the food and the glass is too slick to climb out. |

It's been in my experience that female emerald crabs are alot less aggressive than the males. I had a male that would pick at everything and I mean everything until I packed his bags back to the lfs and traded him for a less aggressive female which has been a model citizen. None of the females have been any problems in my 24 gallon.

How can you tell if they're male or female?

I took as many as I could catch out of mine. They were easy to catch. They love hanging out in the lower branches of pocillipora and think birdsnest corals. They were either picking off the polyps or just stressing the corals. I just pulled the colonies out and pried them out with a plastic knife. Either that or nuke them with interceptor.
