Fish Crazy
Everybody, meet Chubby. 
This was Chubby two years ago; a fat but otherwise healthy oranda.
Here he is today...
Apologies for the bad photo but these guys don't stay still for long and I didn't have anyone to take a picture while I held him!
As you can see, his 'wen' or headgrowth has grown very rapidly and is now covering his eyes. The eyes are fine and intact underneath - they're blocked by a projection over the top of the eye, rather than covering the surface of the eye itself. He has limited vision in one, and no vision in the other one. He has no trouble finding food - they seem to use smell rather than vision - and I make sure he's hand fed anyway so he gets an equal amount as the others who are fully sighted.
Now, the outer surface of a wen has no blood supply. It's kind of like a rubbery coating rather than skin and flesh. I've seen and heard of many people trimming the wen themselves if it grows too large - there's a number of posts about it on goldfish forums etc., with step by step guides.
On a scale of one to ten, how mad am I to consider doing this?
Or if he is still finding food, shall I just leave him to it?
Are there any 'fish vets' who would consider doing something like this? I think I'd be laughed out of the surgery if I asked at my local practice, but surely somebody specialises in fish somewhere?
