Fan Tail Gold Fish and Neon tetras questions

In my tropical tank i've got some neon tetras. One of them is swimming
with it's head facing down. Its stomach is bigger than all the other
tetras and it swims with a jurky motion. It started to do this last
night, but seemed fine this morning. Thing is it's started to do it
again, any ideas? All of my other fish are nice and sociable and the
water quality is fine.

2 albino corys
8 bleeding hearts
2 red whip tails
10 neons
shrimps (not sure how many are left because you only ever see one at a
time!)

Also my girlfriend has some fantail goldfish which i decided to get a
bigger tank at the weekend as they looked miserable in their little
tank. I know absolutly nothing about these. How long do they live, any
special requirements?

Thanks

Ideas:
It might have eaten some dry food quickly (before the food rehydrated)
or gulped some air which it hadn't spat out yet?
