Advertisement So I really want a Portia fimbriata and there's heaps of Lampona sp crawling around my house. I think they'd make awesome pets, problem is they only eat spiders. Through some research, I've found that the grey house orb weaver Zosis geniculatus is a small, communal orb-weaver that is not very aggressive and breeds quickly. Would these make suitable feeders? Could I use them to feed other inverts like tiny whip spiders and huntsmans?
