I did that as well with C.convexus, A.vulgare, P.pruinosus, and T.rathkii, it was a pretty cool enclosure, but I just ended up feeling inclined to separate them into their own containers so that was the end of that. Although it's been almost impossible to completely eradicate the small A.vulgare from the enclosures(The original substrate for each new enclosure was a blend of new substrate and the mixed species substrate, which evidently had tons of baby A.vulgare in it.)I keep a nice mixed container of various species I've found crawling around here and haven't had any problems.
