Fish stop eating and hiding

[blueoverbrown]

It started with a new Bengai Cardinal that I had quarantined. It stopped eating and spent most of the day hiding, moving very little but not laying on the bottom. There was no visible affliction. It eventually died. Next came my long nosed hawkfish. It showed the exact same behavior for weeks and now I can’t find it. I’m assuming it died. Now my chromis is behaving the same way. I managed to catch the chromis, I am currently treating it with Prazi Pro but it is still behaving the same way. The only thing I can think of is maybe they’re being bullied? I’ve observed my starry blenny chasing the hawkfish briefly from his perching rock but it seems very minor. Any ideas or suggestions?

Following, I have a Royal Gramma which is behaving the same way.

Can you post pictures of the tank? Is there enough hiding spaces (the more available hiding spots the more active fish tend to be since they know there’s always a safe place to go).
What’s the full stocking?
That type of behavior is consistent with aggression. Blennies can be bossy but it’s usually worse with similar-looking fish.

That said, cardinals and hawks aren’t the most active to begin with (same for grammas). The cardinals especially tend to pick a spot and hover there. I’ve also found them to do poorly after quarantine (could just be my experience but they do very well in qt but die shortly after going into the dt - it took me a few tries to have one that is thriving in the dt).
Check the chromis for red sores - they are very susceptible to uronema. They are a shoaling fish so it could be stressed alone (even though they have a tendency to kill each other in groups).

Please post a video using bright white light intensity, no blue. Are fish breathing normal or rapid?

I am currently on a trip but I will post pics when I get home if you don't mind following this thread.

The hawkfish was breathing rapidly but the chromis seems to breath normally.

A 55 long with plenty of rockwork as you can see. The tank has 2 mated clowns, a 6 line wrasse (who spends most of the day hiding and hunting and leaves everyone else alone) a starry blenny, a survivor bengai cardinal and the previously mentioned. Lots of hermits and trocus snails and an army of Collonista that come out at night.

I should probably mention that I have been battling Large Cell Amphidinium dinos for many months now. Raising nutrients has been a massive struggle but I think I'm beginning to win, I use a UV sweeper which helps immensely.

With dino, you will have low level toxins but should not affect fish. This has nothing to do with hiding spaces as I suspect possible disease such as flukes, especially if inverts are doing well, water wont be the issue

Here is the requested video. It is currently in a hospital tank, being treated with Prazipro. I saw it eat a few tiny bites of frozen food as they floated by so maybe there is a bit of hope. It sits in that spot and doesn't move. Previously this was an extremely active fish.

Please try you tube version video. This one does not play and use white lighting, no blue please. It takes Prazi 1-2 days to begin taking effect so, may be flukes.

Thanks for the help. Here it is, uploaded to YouTube

I dont see any flaws on the fish and breathing looks normal.

Well now it's swimming like this. Does this give us any more clues?
