Salt- Koi- Goldfish... and Anchorworm
evidently, maybe Leeches as well 8/5/08
Dear WetWeb Crew, Could someone there tell me the correct amount of salt
to use for medicinal purposes-salt bathes. My Koi and Gold fish have a
parasite on them. It looks like a barb or needle sticking out of the base of
the dorsal fin. Also how long should I leave them in the salt solution. I
would greatly appreciate your help. Thanks for your time. John.
<The following is a table modified from "The Interpet Manual of Fish
Health", a useful little book:
---
0.1% (1 gramme per litre): General additive for livebearers or in tanks
where fish show physical damage (i.e., lesions, fin damage). Use in the
aquarium.
0.3% (3 g/l): Reduces nitrite toxicity or to treat physical damage. Use in
the aquarium.
0.3-0.5% (3-5 g/l): To control Hydra. Use in the aquarium for no more than 5
to 7 days, then change water to gradually reduce salinity.
1% (10 g/l): To treat ulcer disease on coldwater fish. Acclimate fish
gradually and then reduce salinity gradually once fish are cured.
2-3% (20-30 g/l): To remove leeches from pond fish. Use as a bath, with fish
put into bath for 15-30 minute dips.
---
In your case, it sounds like you have leeches or anchor worm. Salt dips will
certainly deal with leeches, but anchor worms will need a specific treatment
of some sort. Salt won't help because the free-living stages are in the
water column, so even if the adults are killed, another generation of anchor
worms will find their way onto your fish. See here:

Your local pond supplier may well have a variety of other treatments
available.
Cheers, Neale.>
Leeches
For the reader that was trying to control leeches, Dimilin or Formalin will
work, but care must be used in selecting dosage. Be careful! Formalin
will cause problems in bio-filters if applicable. Also try: http://www.state.me.us/dep/blwq/doclake/leech.htm
