I purchased some Christmas Moss 3 days ago and to my surprise I found two little hitchhikers in it. They are Thai Micro Crabs, they're about the size of a dime and fully aquatic. I have seen them only a couple times out and about but seem to hide most of the time. They're still pretty cute
Thai micro crabs are not too new. They're definitely interesting critters.
They are harvested from a river in Thailand where they live in its fast moving fresh water.
Something about that environment is perfect for their breeding, and we in the hobby have yet to get them to breed. There have been attempts to cultivate the larvae, but they never have made it past 9 days alive.
That's upsetting to me, as these are incredible freshwater creatures, and I tend to only buy critters I can breed in fresh water. If these guys could breed, I doubt I would be as into shrimp as I now am.
Perhaps if you could get a fast current in your tank it may stimulate them to breed?
Oh I'm not actually sure if the water flow has anything to do with it. Many of the people, mainly Germans, trying to breed them agree that sunlight has something to do with it. The larvae go up towards the light. Something like that. I wish I knew more.
