It sounds like your fish has velvet/slime disease
How to be sure
Velvet gives your fish a peppering of tiny gold spots and a coating of slime on the affected areas. Your fish may also become irritable, twitching in the pond like it’s trying to scratch itself.
Step 1 – Treat your fish
- Treat the entire pond using Anti-Parasite Treatment, you can calculate the correct dosage here. Also available, Extra Strength Anti-Parasite specifically for goldfish, Koi and carp.
- Also dose with Pond Guardian Tonic Salt to help support your fish’s immune system.
- Observe the recovery and follow any re-treatment advise on pack or on our dosage calculator page.
- Finally, give your fish some time to recover. Avoid excessive cleaning or adding new fish.
Remember to remove the carbon from your filter prior to dosing.
Step 2 – Check your pond
ONLY USE ONE FISH MEDICATION AT A TIME
Blagdon fish medications can safely be used with Blagdon water and algae treatments.
If you want to re-dose, or change a fish medication, wait 7 days before beginning the new course.
