yeah feeding him is the only issue. . .you would need a ton of liverock + a fuge to grow enough pods (typically)
btw I've been coming across more and more people who have had luck getting them to eat bloodworms (of all things lol). We don't get many in at work , just one at a time every few weeks, and usually we sell them within 48hrs. I had one a few weeks back and tried it and it worked. Apparently they really do eat them ?!?! Dunno why lol. I'm begining to think most people just never think to try offering them.
I do find most saltwater fish will eat them and they are FAR superior nutritionally to brine shrimp.
