At the end of the day you might end up with a communal that works or you might just end up with one big female and maybe an egg sack attached.. :dad :deal

If you got the spiders and the space then why not?
Or try to do a test, take 7 into a smaller enclosure and the rest into a larger enclosure and see the out come.

Hey Cascade, I was thinking of doing a 300 x 300 x 450 size enclosure with a couple of Bark pipes in. I also know that these guys do burrow when they are slings as my one did it. Would be cool to document their movements just like your H Incei communal.

A big and small setup is quite a good idea, would supply more data and a more accurate conclusion. Will be giving this a lot of thought.

I measured one of my big tanks, it is 480 long X 330 wide X 330 high, I would not go higher than 330, if you only putting half the slings into the enclosure that space will be fine, even if you add 15 into that size setup that will be fine.
Just give them a far amount of hiding spots.

Im going to be building an enclosure for 25 and on for 5. So for the 25 im thinking, 610 x 305 x 305 that should be enough space with a lot of hiding spots.

for the 5, im thinking 250 x 250 x 300
