I have kept P.murinus communally to a degree of success (i lost 1 of 12) and i now keep P.regalis communally
Here are others which have been kept communally, with success:
M.balfouri, H.incei, H.villosella, the other Heterothele sp., all Poecilotheria

Tried T ockerti communal. Failed last night when one attached another whilst busy molting.

i forgot about my Psalmopeus irminia s'ling trio

I don't think I'm going to attempt any communals again ,had these 6 h.higas together since last year ,rehoused the other day and one decides to eat the other ,or maybe they just not the best specie to do a communal with ?

Regarding pokie communals I don't think ornata is a good choice cause it always ends up in one fat spider

I know Avics can be kept communally. But they need alot of space.

My friend Johan had 10 Avic Avics in a communal, a few escaped but there were

still around 6 or so left.

:rock

i've heard of a few H.incei fails though. and i've seen it myself. im keeping 50 S.calceatums communaly for over 2 months now and havent lost one yet.
