This is great. A cave and feeding after dark will not be a problem I have them in my saltwater "lagoon" so reaching them is not an issue. I'll just put them in a spot where I can feed them with a turkey baster.
I successfully fed my lil suns tonight. I put them in a flowerpot, stolen from my clowns, facing away from the light. They seem to like it there. Of course, I have them for only about 24 hours.
