Pond Boss Forums INTRO Questions & Observations Odd fish defects?

Is this common to have defects in fish?

Is this a problem or common disease?

I have caught one perch like this too but put it off as the GBH nailed it and it lived. The fish still feed and swim normal but maybe more to the right. Tee he he.

Cheers Don.

Will post up pictures when I can. Something is up with adding attachments.

The fish have a crook in their tail from their anal fin back. All have had the same crook in the same direction.
