Hmm... first thing I seen was mal-nourishment when I looked at the photos.
I'm specifically looking at the spinal deformation behind the dorsal fin. If
that's due to UV, that's quite interesting, I'v never seen that effect
before.

A while ago I asked about a strange disease which had all but wiped
out my main tank: roughly 50% died within the first 24 hours, and most
of the remainder in the following month. The symptoms (except in the
initial losses, where no symptoms were seen - the fish just died) were
a white blister or ridge along one side of the fish, never on both
sides, and some of the fish suffered 'convulsions' as if there'd been
nerve damage.
Through it all, most fish seemed perfectly normal, until they suddenly
would develop symptoms.

It was deemed then that the most likely culprit was Flexibacter
disease.

Well, I've now put together a webpage with some pictures of a diseased
fish - given that this is what it looked like, is it likely that it
was Flexibacter?

The reason I ask is because it's been suggested to me it's burns from
the UV radiation of the metal halides, and if so it could happen
again.
