Some sort of neurological problem? I have noticed on many occasions that
he has an issue turning left, so he somersaults and does a right, like a
swimmer at the end of a length. I have had the light back on temporarily
and he has gained control somewhat. Angelfish seem to go to sleep when
the lights are off and switch off their visual system. To some extent
they need to feel around, even when the lights are back on, and "wake
up" gradually over 15 minutes or so.
I've put in some activated carbon, switched on the UV lamp, turned up
the temperature, and a left a small light on, just in case. Now that I
know he loses complete control at night, I'll have to look into a
possible cause and a cure if possible.

Just a thought, modify your filtration system so that there is less
turbulence. I wonder if the fish's equilibrium would be influenced if
the filters were turned off temporarily (just as a test sometime, when
the lights are off). This allows navigation by feel, which is normally
masked by filter noise & turbulence. This won't solve your problem,
just gather information.

I moved 2 angelfish to a separate tank and over the coming month both
lost their orientation skills and died. I have assumed it was a swim
bladder infection.

I'll check that out. The fish appears to have a very slight paralysis.
Could be anything. Even a fish version of MS. I could imagine him too
being depressed over the recent loss of his breeding partner which I had
to euthanize because of a tumour or egg impaction. Do fish show signs of
loss? He's all alone now!
Nikki
Most cichlids which form breeding pairs will display reactions to the
loss of a partner. Ask any Oscar owner if their fish is temperamental.
However I don't think it would explain what you are seeing.

Restoring some information, such as vibrations through the lateral line
should help (by decreasing the turbulence in the water), but with the
limited vision in one eye, I suspect a bacterial disease in the brain or
around the cortex, and that's not likely to get better.

Yes, it seems the problem is exacerbated by dim light. Today, the
angelfish barely showed any problem with control. Last night, every so
often, it looked as if it got a rudder stuck full on and span out of
control, slowly and "majestically", if that's possible. There wasn't
much sign of panic. Suddenly, the rudder would became unstuck and normal
control would resume. Interesting. I also find that this angelfish
orients itself so that it points towards ambient light when the
fluorescents go out. This means you can find it listing at least 45
degrees. This has always been its "normal" behaviour, regardless of
recent events. It has no problem locating the food I put in the tank, so
I'm not sure if its vision is affected at all.
Nikki
Well, at least the listing is normal. Fish orient themselves according
to the source of the light. It's most noticeable with tall slow fish
like Angels.

He doesn't, say , what the filters consist of "net max" My Angles hate
strong current, by way of a power head, but normal canister filter
inlet //
output , like UGF's don't seem to bother them.
I agree.
I tried a power head once. It was horrible for them no matter where I
aimed it.
The Magnum350 canister filter doesn't bother them a bit.
They swim through the current streams no prob. They simply learned
quickly to turn their body to one side so the current hits them just so
and they cut right through it.
All my Angels do this.

Interesting. My angelfish that had the tumour and died, loved forcing
herself into the current from the powerhead. She seemed to gain some
relief from the physical exertion. Also, I think she found it easier to
keep upright in the stream, like an arrow flying through the air.

His condition does seem stable, neither getting better or worse. Eating
is not a problem. Maybe it's a very slow degenerative disease? I've just
purchased two adult angelfish which I've placed in quarantine. I do hope
he gets to meet them as he was looking despondent a few weeks ago.
I've just calculated that he must be 4 years old. I wonder how long
angelfish live?
Nikki
ROFL! "Head over fins" creates a great mental image.
LOL>..yeah...it looks just like what's in your head! = )~
Nikki
Generally, and in good health, good water maintenance, 8 yrs on
average.
