I amend that statement they look like more 1-2 in body, but the legs look thicker than thai crabs. Also the thai crabs have more curved pincer arms whereas the mud crabs are more of the more regular crab shaped pincer arms .
I think the biggest difference is size and how the pincers are positioned. The thai micro crabs seem to have smaller pincers and hold them folded underneath the body. With the mud crabs they seem to have bigger pincers and hold them out in front.
I have been noticing empty shell snails, but I attributed it to being there before I put the crabs. So yesterday I put some more Rams snails of different sizes into the tank. I just noticed that there is a snail shell that looks broken with a dead snail partial in it. It could be that I smashed a snail on accident when transferring them. I guess I will need to see if more empty shells show up.
Re: Mud Crabs Have Arrived --- Rhithropanopeus harrisii
Here's an update (Hope you don't mind!) These guys are very hairy this one on his side keeping at least one "toe" out of the water. I put a small amount of spirulina in the tank, thinking he's catching it.
Yea those are Thai micros. They were what I was originally going to get for the tank until someone else started the thread about the mud crabs. According to some of the articles, on mud crabs, they can and do have a full life cycle in fw bodies of water. Hopefully it can be repeated in the aquarium setting. If i remember correctly Thais also can do a full life cycle in fw but no one has been able to repeat the process in the aquarium.
One of my crabs is bigger than the rest. Not sure if it is a female and the others are male because it looks bigger. I wasn't able to get pictures of it to show size reference. All the pics I have so far are of the smaller crabs.
ROLL TIDE ROLL!!!
