I was interested in getting either one of the two I am not interested in the "really pretty stars"

. For some reason I really like these two because they look like something that comes out of the aliens anthology

! Although I read/heard that you feed them twice a week. But food is no problem since i live in Florida you just have to go to the docks in the moring to get fresh food. But a couple of questions about them:
1. Which of the two are more hardy.
2. what is really the difference between the two.
3. does the
serpent star crawl on the glass (not particularly wanting but Ok i guess none the less)
4. does anyone have any experience with either one
Thank Brian
