Re: [Killietalk] Pupfish problem
Unfortunately most people who handle pupfish think all you do is add salt to
your water to increase the TDS. Increased hardness is a result of dissolved
salts picked up from the arid, evaporite soils of the west. Those salts are
not sodium chloride but usually a variety of alkali and alkaline earth
carbonates.
What is being seen is a case of bad water quality or more properly the wrong
water chemistry. You also see this as a result of prolonged periods of time
where you don't do water changes. It is also probably a result of the wrong
chemistry. Even if you match hardness, your mineral balance is entirely out
of whack and efforts to even osmotic differences between different chemicals
is probably what is causing the deformity. You will probably not be able to
correct the problem you created and good luck working with the deformed fish.
You may probably get them to reproduce as long as you maintain a clean,
consitent water chemistry from this point on and tend to nutrition needs.

I posted a couple of threads about swollen gills on desert pupfish in the
general discussion before realizing I probably should be in this forum. We
are caring for Desert Pupfish that are showing signs of gill inflamation,
with red and swollen gills (some quite severe). It was suggested that the
tank is deficient of salts, and the additon of these might help the
situation. I have done a 20% water change with salt in the new water, but
today while I was watching them eat, it appeared that the two pupfish with
the most swollen gills would swallow food and have it exit their gills. Is
this possible? If so, is this indicative of something other than a salt
deficiency?
Thanks.
