Folsomia candida is not a tropical springtail, it would take you a few second search to cofirm. Getting an identification on springtails is not easy and there are many species. Dart frog people also put scientific names on isopods that aren't even close, the wrong name is not really better than none.Actually the temperate springtails ( Sinella curvisetta) are much different than tropicals ( folsomia candida) there are also about a dozen other species from several other genera available for sale. Tomocerus are the largest available, but reproduce slowly
