Unfortunately, none of the above will sustain him over the long term. These guys really need live pods to thrive. This is a perfect example of why it pays to have a really good LFS that will educate newer tank owners, as well as doing your own research on the species before making a purchase. I've never met a LFS that wouldn't place an item on hold for 24-48 hours so you can do a little homework. Really hope this guy makes it for you.
