Hi,
I have recently moved into a new place in san diego with an empty fish
pond (6 x 4). I filled it up and put a few water plants in it. They
did great. Three weeks later, I put in some small comet goldfish.
They appear to be doing fine. BUT, I have noticed at times they are
at the surface not moving and what appears to be sucking up air. In
addition, since I put in the goldfish, there has been airbubbles
floating on the surface. I have caught the fish "burping" up these
bubbles. Not alot of bubbles, but bubbles that weren't there before I
added the fish. I have not done any water treatment nor do I have a
water filter. I am trying to do it natural. Are these normal
observations? Also, does anyone possibly have insight to the
reasoning behind my observations.

Thanks alot!!

Dan
