mine dont go after shrimp i have them with crs but there is a fair bit of moss in there too.

i love the blue shrimp, my greens get crazy colors like that from time to time. not sure what they really are though. the crabs are cool but so not a fan of pinchers of any kind in my tanks lol

Are they Green Neos? The crabs pincers don't seem all that strong, but I really haven't seem them use other than grabbing food and walking away with it.

I'm not sure if there is a way to test pincer strength lol.

I wish there was so you could give a definitive answer.

I know my CPOs have fairly strong pincers. I've seen them do neat things with them. Including grab my planting tongs to show them who's boss.

It looks that way. They probably have burrowed under all the ss mesh and ceramic tiles.

In the fish store (in Seattle, btw), I think the clearest one in the photo was standing. In the bowl they're huddled down trying to hide.

In the stance he held at the shop he looked very similar to our spider crabs, only tiny.

Re: Mud Crabs Have Arrived --- Rhithropanopeus harrisii

Your crabs look more like the kinds we find on our beaches with a flat face, while the ones I have have a rather pointy face.

A pic from the Net... A thai micro crab with a Tiger shrimp. Looks a lot like mine.

Re: Mud Crabs Have Arrived --- Rhithropanopeus harrisii

They have long hairs on their "arms", thinking some filter feeding goes on.

Based on that pics. Yours look more like Thai micro crabs. Longer legs and more curved pincers.
