one last question
So my blastomussa that I purchased 4 days ago it’s mouth is gapping open and you can see his skeleton! At night he shows A LOT of his skeleton and during the day he shows a little and goes through spurts of gapping his mouth! This is my first blastomussa so I’m looking for some advice...anything really! I called my local fish store and he said as long as there is color I can bring him back and exchange that maybe I just got unlucky...
What should I do? Is him gapping his mouth mean he’s unhappy?
