What a fantastic animal. Whenever I think of egg-eaters, I picture the brown/olive-colored species, so it's nice to see one that's a little bit more colorful and patterned.
This is a different image than what I saw, but even in this one, there's actually a lobster. Upper right quadrant. I think my eyes are magnetic to lobsters or something, because I saw that one almost immediately
I wouldn't risk it; the fungus which makes them glow is likely at least semi-specific to them and their environment. Experimenting in captivity is possible, but these guys don't reproduce all that easily or quickly from what I've heard (I had a few but they all died), so I wouldn't risk feeding them some random species of bioluminescent fungi to get them to glow.
