I have 3 Daddy Long Legs and I want to put 2 in the same enclosure so I can get another spider. I haven't been able to find any information if they would eat each other, so if someone could tell me it would be greatly appreciated. Cheers!

You will need a fairly large container and an adequate food supply, otherwise they can turn carnivorous
