Apologies, I know this is a true spider not a tarantula but I felt like unrelated wasn't a good place for this question? Anyways I was wondering how hard it would be to keep a diving bell spider? I wonder how it would do in a fish aquarium with fish that don't pose a threat to the spider like guppies? I know the spider would eat the guppies but thats the reasoning behind it.. technically it would be a self sufficient habitat with basically only needing to add fish flakes. I'm looking forward to seeing what everyone thinks.
