Hisser mites will live on any Hisser species if given the opportunity, I have mixed tank of males and the mites go on every Hisser equally as much. Again, its normal to have Hisser mites and is good for them.Not really true. I have a bunch of different hissers kept in the same room (regular, wide horn, flat horn, tiger, Halloween), only wide horn and tiger hissers get mites because some of them were introduced from a breeder who had mites in his colonies.
Hisser mites won't do harm to anything unless they get overwhelming or you're allergic. Grain mites in substrate is safe for roaches but bad for tarantulas, mite issues differ from case to case.
