Will communal scorpions cannibalize each other after moults?

I've been wondering, what if my babies(Heterometrus sp.) moult, would they be vulnerable to their own siblings?

yes all scorps munch on each other after molts ,just some more than others

which means keeping babies in a community tank isn't exactly a good idea?

If you're really attached to them, I'd keep them separate for now. I keep all my emperors together (1 or 2 still have a molt left in them), because they tend to be protective rather than aggressive during a molt and if I lose one it isn't like losing something expensive.

if well fed SOME species will not cannabalize. An example: P.imperator, M.martensii.

Your hets should be pretty safe. I've lost one out of five emperors and two out of ten hets, so it seems to hover around a 20% cannibalism rate (for me anyway).

Although for the emp that I lost, I don't think it was post-molt cannibalism, as I found a hardened claw. The only scorpion that I had die immediately after a molt never hardened.

=( the problem is I've got a rather large terrarium for 'em, what should I do? transfer 'em separately to something smaller?

I've got 4 babies in a 13x7 terrarium. I guess thats even huge haha.

That's a good thing, no?

Now I'm just worried I'll end up with something less than 4 after moults. I only have 4 and 4 isn't exactly a large number.

Ah, good suggestion. Thanks Connie!

What is the best proven method to keep young 3rd instar Hets.? Communally or separately?

I have no idea sorry. I would say all well fed then all good to go, but as you only have 4 of the little ones I would put into their own containers. I mean you could still lose one or two to a bad moult. So I guess with scorpions you never can tell.
All together they could all be fine and in their own little homes they could all be fine. Do what your gut tells you to do

They do fine communally; cannibalism isn't nearly as big of an issue as it is with buthids. In fact, my baby hets and emps all share the same hide all the time. I lift it up and I see a little pile of scorpions.

The best way to keep any scorpion is by it self. But I see no problem keepint your scorpion comunally. Unlike Mike I have kept mines all different sizes and have had no canabalism at all. Not even during molts.

For reference, I'm on the "unlucky" end of the scorpion-keeping spectrum.

Hopefully I do not share the same luck as ^.

I've only got 4!

i think separate them just to be safe...
