Several fish flashing, should I be worried?

[BSej]

Sometimes wrasse “flash” diving for food. Even a regular scratch now and again doesn’t always mean flukes. Ich usually doesn’t cause scratching.
The fish are still in hypo, right? What is the current salinity?

They are still in hypo, yes. Salinity today is ~1.0092. I was measuring salinity daily, but I don't any more as it doesn't seem to change. I have an ATO that seems to be doing its job. It does fluctuate in the 4th decimal digit a tad (the '2' in today's measurement) but has never hit 1.010 to my knowledge.

I'd say this is just idiopathic scratching then, very few flukes species can survive full hyposalinity like that. I'd say that NONE can, but there is a species of brackish water fluke that might be able to, but it is rarely seen in pet trade fish.

The Formosa is disappearing or sleeping earlier than it used to. Around 4-5pm now instead of 8pm. I see one white spot on his fin, not sure if it is a concern. It is still active and eating in the morning.

Looks like it could be just a broken fin ray.

He's barely moving now. Hides for most of the day. Didn't eat just now when I fed.

Can you post a new video? The one from two days ago didn’t show any issues.

Didn't see him again until he turned up dead. I've begun raising the salinity after the 35 days and I'm not sure the treatment worked. I see some spots on one of the clowns when he swims under the light. Only 5 fish remaining so if anything I'll just QT them..

Hey guys I am wondering if I can hook my refugium back up to the display. It's been sitting in isolation for the longer than the period of quarantine so there shouldn't be any risk of parasites. Anything else I should be worried about? The chaeto is still alive along with a lot of other critters in there.

Has it been isolated for at least 45 days? Seems shorter than that. 30 days is the absolute shortest clearing time and that’s only for fluke eggs.

Yes today is day ~48
