It sounds like your fish have an accute internal bacterial infection
How to be sure
Your fish are unwell or may have even died suddenly with no obvious reason. This can be due to invisible poor water quality and can only be discovered by testing your water. If test results prove ok then it is most likely an internal bacterial infection which doesn’t always have visible symptoms and can affect the fish very quickly.
Step 1 – Treat your fish

- 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 with treatment.
