Answer 1

Check (and fix) your water chemistry or temperature right away!

He may just have succumb to a bad chemical or water condition because he was the weakest of the bunch. If you do not take measures soon, these conditions often get worse very quickly and effect even your healthier fish as well.

Good Luck!

Answer 2

It may be old and sick.

Answer 3

How old is this fish?

I'd quarantine it in case it picked something up. You just can't save some of your fish.

Answer 4

It has swim bladder disorder and it may have a parasitic infestation.
