As chris said, he's written plenty of info in the saltwater inver profile sectionHow big are they likely to get in captivity and how long would it take to get to full size???
Thanks for letting me know about the silver side ill make sure thats not fed if i do get a mantis.
As for the snails what type is it you feed it?? and do you get a load and keep them in your normall marine tank and pick 1 out when its feeding time???
