I have two new azure damsels in QT. One is feeding well but the other (larger) appears to not be closing its mouth entirely, not eating, and every so often stretches or gaps its mouth as if it has something stuck in its throat its trying to dislodge. It's also become more skittish the last couple days (initially was very bold) hiding behind rockwork.
Any ideas what could be the issue?
