I don't understand the kind of dip you gave the fish. You matched the alkalinity for the dip? A freshwater dip should have a significantly low alkalinity.

Dipping a fish because it doesn't eat is sometimes the wrong path. The fish isn't eating because of a stressor. The FW dip is an additional stressor. I can see one stressor used to correct another stressor (e.g., a dip to remove parasites), but the fish is in the display which would still be infected.

Thanks for the movie. Is that LR in there? Either you are doing above and beyond in keeping the tank clean, or that tank is very young. Maybe too young for what you added? Maybe do extra reading on this: The Mature Aquarium

The added bio-load to a system with nothing? in it previously is a shock to the system. The other inhabitants are doing fine? For a while. Their lives are likely significantly shortened. Only the Anemonefish are showing first.

The quarantine of fish is not only to verify their health, but to train them to eat.

The acquisition of Anemonefishes in my opinion requires an immediate treatment for brooklynellosis. It's just so common among these fishes that treatment is called for even if they aren't displaying. Above average 'breathing' is one symptom of the onset of this disease.

Are you aware that some online sources get their fish drop-shipped from the wholesalers and importers? Such online sources actually don't stock everything they sell. I go to LAX wholesalers and find all sorts of pre-printed boxes from many familiar online vendors. If online is your only source, then I can appreciate the scene. But try to go the extra 'miles' to an LFS, breeder, or other aquarists, for fish acquisitions. A sometimes clue is seen as a stamp or carrier mark on the label or on the package as to the city of origin, regardless of the printing.

The above might cast disparity about advice as to what the fish was or wasn't eating at time of shipment. The online source may never have even seen the fish you have and could be repeating info third hand (or fabricated).

At this point in time, I have no clue as to which of the above stressors and the additional few dozen not mentioned stressors are at work here. There is a chance the fish will settle down. You may try to figure out and remove or lessen as many stressors as you can.

If the fish were eating well and properly fed, they can live a few weeks without eating.

Good luck!
