Advertisement Why are jumping spiders not in the pet trade? I have wondered for a long time now why jumping spiders are not more popular in the pet trade. There are only two reasons that I can think of and those are the size and the lifespan. Other than those two reasons I can't think of any more. They are very easy to breed and keep, they all have funny little personalities, they have a great feeding response, and in my opinion they all look amazing. So i just wanted to get some opinions as to why they aren't more popular. Also I'm new to this forum so if I'm in the wrong section please tell me.
