Report in this month's Goldfish Keeper's Monthly magazine.

quote ... " TRISTIE's syndrome ... AIDS for goldfish ?."

" Latest scientific analysis has proven that there is a fatal,
malignant,
genetic condition that is now affecting countless numbers of male goldfish
worldwide. It's cause is believed to be the result of male goldfish
attempting to mate with each other.
Symptoms include an involuntary reverse digestive system (passing faeces
through it's own mouth, on a regular basis) & complete loss of colour /
total
transparency ....... resulting in becoming completely invisible &
unnoticed/ignored
by every living thing around it. Eventually the affected fishs' mouth
becomes so full
of it's own faeces that ( as all the other fishes can't help but ignore
it ) it drowns,
choking upon it's own ****.

Just thought I'd share this with you.
