What causes Deformity in Stingray Pups?

[Mobatic]

A buddy of mine had a pair of pearls that gave birth. It was a single pup and it was born with a tail that's docked. I was wondering if the case is maybe from being inbreed? The reason I asked is that the pair he got was from two different source so I was curious to hear any thoughts.

probably no different than a birth defect in humans....

Some people think stress could be an issue, it could also be down to heavy metals in the water or other water quality issues.

First litter? From what I have read on MFK, it seems litters 1,2,& 3 usually have more problems (defects, still born, ect.). Not sure about WC adults breeding in captivity for the first time.

Young parents, environment stress (high temps/low temps, pH swings), nurishment during pregnancy and over all health of the mother while pregnant are all factors we've linked to pup deformation.

Yeah, its a fairly young pair and I believe it was the first litter. Its a nice pup but just the tail that an eye sore.

Genetic mutation.

I agree but don't know to much...

If it's only a bend in the tail, it could be as simple as positioning of the pup while it was developing. I've seen pups get twisted/bent tails from getting the barb stuck in the wall of the uterus.
