It sounds like your fish has an internal bacterial infection
How to be sure
Bacterial Infections can cause your fish to have open sores or ulcers on its skin. It feels quite poorly and may also be gasping for air at the surface. The ulcers might have also started to grow some white/grey fluffy, fungus around them too.
Step 1 – Treat your fish
- Treat the entire pond using Anti-Ulcer, you can calculate the correct dosage here.
- 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.
