Hello! I've had a green mandarin for a little over 24 hours. I haven't seen it eat, but I know that there are tigger pods
in the tank since I just added a bottle to help repopulate. I checked the water parameters prior to adding the fish and they were good. My only other fish (two clowns) are doing just fine. I've previously had a mandarin in the tank which lasted for over a year, but this one isn't moving around or hiding. It's just sitting on the sand. It's gills are moving slowly and it will only move when prompted (which is still slow and delayed) and there are white spots on it. I'm not sure if it's sand since it's just sitting there or if it's something else. There also seems to be mucus over the gills. I got it from a fish store that I've never had troubles with and it was healthy (or at least it appeared to be much healthier) when I bought it. Could it even get sick this fast? And, if it's sick, is it my tank or was it the pet shop? I just paid a bunch of money on this fish so I don't want to just let it die nor do I want to risk spreading illness to other fish. Something I do know that is different about that store's water is that they treat it with copper. Could that have something to do with it?
