hello, if you can share a clear video of the fish exhibiting this behavior, that would be helpful

Look for a Rusty Magnet, including taking your pumps apart. If you’ve had kids near the Aquarium, look for pennies in the Aquarium, they can disappear into the sand quickly. It’s the Zinc in the Pennies, that cause the problems.

Will have to wait till my next fish does it.. as it was my dwarf lion fish in the last two days.. but didn't video.. and already removed him.. to reduce him killing anything else in frenzy..

So when all inverts are healthy, then it is disease.

Are the fish breathing heavy at all?

There are flukes that are not visible to the naked eye (need a microscope) and velvet can kill without any spots showing.

Also my blue cheeky goby is unaffected?

If fish are dying off quickly that indicates disease or water chemistry causing lack of 02. Since they are not gasping for air per your observations it is probably velvet. When did you last add a fish? Do you medically QT fish prior to DT?

Video does not play.
Are fish eating? Breathing normal or labored?
Please try a you tube version video under bright white intensity of at least 30 seconds

What is age of tank?

Well fish have to be theraputic copper for 30 days to treat disease so "being in copper" could mean anything.

Most LFS don't keep fish 30 days nor do they run therapeutic copper, usually they run sub therapeutic, enough to keep disease low but not cured.

First blush I would say possible electrical shocking. Short in heater or pump or other equipment that comes in contact with water. Sometimes you can put your finger/hand in the water a feel for low electrical volt.
