Thanks for the prompt for an update.
Since then I've moved him to my main tank. He's had a bit of a rough time, as he's had two bouts of fin rot (first his bottom fin, now his top). He's still recovering on his top fin, but it is much better than it was before. Oddly, no other fish in the tank had any rot issues.
He's going to be an only angelfish. He's in a community tank now, though, and he is getting along great with his tankmates!
Anyway, you're right about the bloodworms. Bloodworm day is his (and my ADF
's) favorite day!
