Amblypygi have different temperaments and feeding responses just like different tarantula species. While my Euphrynichus bacillifer is very shy about eating, and never does it in front of me, both my Phrynus attack their food within moments of me putting it in their enclosure.
They seem to hang out together quite a bit.
Also there are two P. marginemaculatus on top of each other there. Why? No idea. There's plenty of space on the bark. They don't seem aggressive towards each other.
Wish I could have taken this shot on a good camera instead of quickly with my cell phone.
