Really like my new pond, finally seem to have the surrounding drainage
problem and the Mysterious Water Loss After Heavy Rain problem fixed,
so now I'm thinking...

How about if I run black gas pipe out to the the back end of the pond,
put on a valve there, then something like icemaker tubing into the
pond so that gas bubbles up near the center, then light it.

I wouldn't run it all the time, but it'd be a cool effect for parties.

Would there be any adverse repercussions to the fish?

I think the bubbles would be too intermittent to hold the flame unless
you were running more gas than you'd care to. (Unless you use a bubble
diffuser?) Maybe run the pipe almost to the surface so there's more of
a steady gas stream? That'd cut down on the water/gas interaction, too,
in case of any adverse reactions with the pond environment.

LPG forms a flammable mixture when mixed with air.

The flammable range at ambient temperature and pressure extends between
approximately 2 % of the vapour in air
at its lower limit and approximately 10 % of the vapour in air at its
upper limit. Within this range there is a risk
of ignition.

Outside this range any mixture is either too weak or too rich to
propagate flame.
However, over-rich mixtures can become hazardous when diluted with air
and will also burn at the interface with air.
