I got 2 yellowtail Damsels 3 days ago and they're still hiding in the rocks 90% of the time. I understand they're new so might take a while but they're the only fish in the 15gallon tank. I setup a time-lapse cam to see if they come out when I'm not around and yeah they do. Which is fine but I'm not sure if they've eaten. I fed mysis 2 times so far, once on 2nd day and once today but didn't really see them eat because I walked away. ( they hide when I'm there ). Also got copepods when I got them so they have something to hunt etc. Anything else I can do or do I just have to wait ?
