B. dubia+b giganteus+b cranniffer

[joshuai]

hello i got a dubia colony and i got sick of takeing care of 8 craniffer so i threw them in with the dubia, and i did the same with five giganteus adults will they cohabitate with no problem, oh ya there is 4 hissers in there too so far there doesnt seem to be any problems and the dubia are producing so i dont think the nimphs are getting ate or anything any input would be great. and there isnt any tore up roaches or anything either

There is a chance of interbreeding between anything in the Blaberus genus. B. craniifer does regularly interbreed with B. fusca, and in theory could breed with B. giganteus (though hopefully not if conspecifics are available due to the difference in size). I'm not sure I'd want to risk diluting B. craniifer if they are really true death's head and not hybrids, but I suppose that is at your discretion as a keeper. I do hope the tank has accomodations for both climbing and burrowing species and a barrier for those hissers though; a lot of folks don't bother with a vaseline barrier on B. dubia tanks since they can barely climb the lip of a food bowl without falling down, but the hissers and especially their nymphs DEFINITELY need one.

ETA: Also, if you plan on selling craniifer or giganteus nymphs in the future, you NEED to inform your buyers that they were in a mixed-species tank. Hybrid nymphs look almost identical to non-hybrids, and nothing will tick of a true collector more than plopping down $$ for either species just to find they've been jipped and have hybrid stock.
