Is my bicolor angel losing its appetite?

[Korvix]

Topic says it all. Just got a small Yellow Tang and a dwarf Bicolor angel, both still pretty shy since they've only been in the tank less than 24 hours. Tang's already munching on the green algae and the frozen Brine with garlic guard - no problems there. Angel, on the other hand, isn't having it - he's picking at the rocks, but I don't think he's actually eating anything stuck to them.

I had no idea these fish were finicky eaters, so I'm gonna grab some angel-specific frozen food tomorrow and see if that does the trick. Should I be worried or is he just still getting used to the tank? Other than not eating, he looks perfectly healthy - when I chill and watch, he swims around, letting the cleaner wrasse and skunk shrimps snack on him while he grazes the rocks.

Dwarf angels can be notorious for grazing on rocks all day, some are just naturally picky eaters. Have you tried offering him some mysis to see if that's more to his liking?

Some Bicolor angels are just gonna do their own thing and prefer grazing on live rock, it's not uncommon for them to be a bit finicky, depends on the individual fish I suppose.

I'd also like to add that many marine fish can be stressed and take a few days to start eating. Give him some time and he should be fine. Also, give mysis a shot, and if that doesn't work, you could try live brineshrimp as well.
