Geosesarma mating behavior

Hey everyone!
I haven't really posted over here before, but I thought I'd say hello and post up a recent video of my Geosesarma crabs. Hello!



It's really rare to see such detailed mating shots, I haven't found much on the subject online... so I'm happy to have caught it without disturbing the act. I've had this group of crabs for months now, but this was the first time I was able to catch them mating on video... only the second time I've ever seen the activity, even though there are dozens of offspring in the tank.

Two crabs just trying to get down on some afternoon delight, and next thing they know, photos/video of them doing the nasty are plastered all over the internet. I love the look of shock on dude's face, like he's contemplating whether or not to stop.


Welcome to the forum, buddy!

Are all the Geosesarma crabs the same in that they live in freshwater and give birth to fully formed baby crabs? I have seen a few different colour variants and I wondered if any of the geosesarma species needed brackish water or a larval (?) stage.

I really like that 'caught in the headlights' look in the picture too. Hilarious.

lol. thanks! yeah, the expressions they appear to make can be really funny... but I do sometimes think that their eyes are misleading, as the black in the center is visible from all angles at all times... like a pupil in the center of a clear sphere that looks white.

and evilhorde: yes, all Geosesarma are the same in that they do not require or like brackish water. They are freshwater forest crabs, that spend much more time out of the water than in.

I also wanted to mention... a lot of people have mentioned to me that they didn't watch to the end... it's long, I understand... but for people really interested in the physiology of it all, the dismount at the end of the video offers a little bit of detail into how the female physically opens up for mating. It's pretty wild really.

This tank of Mellows was actually featured for its entire build in a series in TFH's Adventures in Aquascaping. There are some pics on the TFH blog here: http://www.tfhmagazine.com/blogs/cat...n-aquascaping/

He has juveniles available! I went and visited him a fwe weeks ago and was blown away by how active and engaging the juvies are. The tank was fascinating to sit and watch.

Your not helping Msjinkzd :P I'll have to do some more research. How big of a tank would they need? Or have any links to some info?
