Advertisement I decided yesterday to create a terrarium filled with rotten wood and such (a detritium I think it might be called?) and added five isopods. Today I went outside and caught several millipedes to add, one of which was a two/three inch long red black and yellow flat millipede. I have seen this species or a species similar in appearance but never kept it. The first time I saw themillipede I looked it up and the closest visual match was this http://en.wikipedia.org/wiki/Apheloria_virginiensis but I know that I can't reliably determine species from a photograph. The page says that this species (if this is that species) secretes cyanide compounds that aren't plesant if they get in your eyes. Do you think it will poison the other inhabtants of the tank or me? Are there any millipedes that can kill people?
