Adrian, Belly sliders are simply fish with a swim bladder that is not
properly formed. Several theories abound about the cause. Some folks
will say the young fish did not get to the surface soon enough to "gulp"
air and thus fill the bladder. I don't think that this is a good
explanation because there is not a good opening directly into the
bladder in most fish. I feel that the bladder fills with internally
generated CO2 and something simply goes wrong with this system.
It seems that when I force hatch fry there is a greater chance of
getting bellysliders than if I water incubate. Perhaps these fish are
simply too young to hatch and are not well developed enough to have the
bladder developed completely.

Subject: [RML] Body Sliders

Body sliders are what I call rainbowfishes that haven't
developed their swim
bladder correctly. They usually swim with their head up a tail
down and swim
with jerky movements. Sometimes I end up with a lot of these in
some of my
spawnings and other times I have none. What has been other list
members
experience with this problem and does anyone know what actually
causes it or
does anyone have any theories on this subject.

Adrian.
