It sounds like your fish has Carp pox or tumours

How to be sure

Your fish has some irregular lumps, bumps and growths under the surface of its skin which could be tumours or viral growths. These issues are not directly treatable, although supportive measures will help your fish feel better.

Step 1 – Treat your fish

  • Treat the entire pond using Stress Away, you can calculate the correct dosage here.
  • Also dose with Pond Guardian Tonic Salt to help support your fish’s immune system.
  • Observe and follow any re-treatment advise on pack or on our dosage calculator page.

Remember to remove the carbon from your filter prior to dosing.

Step 2 – Check your pond

  • When fish are sick, always test your pond water for excessive ammonia, nitrite, nitrate or pH imbalance.
  • Treat any unhealthy results to rebalance your water quality and give your fish the best chance of getting fighting fit again.
  • Check all your equipment is working properly – especially filters. Carry out any maintenance needed, or replace faulty or broken parts.
