Mini crab species other then Fiddlers and RCC's

I've done heavy research on both but was wondering if there are any other distinct types of mini crab available as pets.
I've already heard of the Thai freshwater crabs but my tank is going to be brackish so this might exclude them. I've also heard of rainbow/patriot crabs but they don't quite fit the size criteria I'm looking for.

Anyone seen or heard of other types of mini crabs in the hobby?

I remember seeing something about Microcrabs...Think I saw them at Bobstropicalplants.com. they may be Thai. And he had panther crabs. Believe it said they are fully aquatic as well. Don't know if they are brackish

Funny because that's the one I've most been reading on lately though there's little info to be found. Most indications say they're freshwater but I have to imagine brackish water works just as well
