My crab is very active and eats a lot, I’ve had him for most of my life. (My tank conditions/temp are fine) But I noticed when he’s sitting still / tucked slightly into his shell he’ll sometimes do these funny little leg / body shakes. (Almost unnoticeable, you really have to stare to notice)
He sometimes does this in his moss pit (sphagnum)/ when he’s sleeping. I don’t really think much of it since he’s showing no ill signs and is still acting perfectly normal.
Maybe I’ll take a video of it when I witness it again. It doesn’t happen all the time, I’m just curious and want to make sure it’s fine behaviour
Thanks everyone
On a side note: I did recently move him into a bigger tank, all the sub/deco from his old tank went into his new set up. He absolutely lovesss the space and loves climbing everywhere. He shows no signs of wanting to dig to destress/hide. He’s more active then ever! Like I mentioned! (But maybe he’s still a little stressed?)
Edit: he’s also a medium sized crab, don’t think that has anything to do with it. But idk haha
