Black markings on head an gill

Recommended Posts

Can anybody Identify the disease on this fish, he is around 5 years old and has never had any health complications before apart from a benign growth on his back.

If the issue can be identified then can a treatment be recommended. 

I have checked the ammonia content of the pond and it is safe so ammonia burns should not be the issue.

the fish himself is acting normally. 

The black marks are located on the gills, above the mouth and on the nostrils

Ponds need water changes.  An absolute minimum should be 10% changed weekly.  

0.5 ppm is not a safe level of ammonia.  Zero is a safe  level.

 What kind of water additives or conditioners? Only ever pond weed treatment or medicine.  If this means you are killing pond plants it may explain the ammonia, which you should never see in a healthy pond.

Thank you for for the advice. I will start preforming the water changes.

Id like to add that I accidentally said pond weed, the treatment I put in my pond is for blanket weed and thats only when it gets out of control.

You can remove blanket weed mechanically.  https://gardening.which.co.uk/hc/en-gb/articles/213512269-Blanketweed   It makes a good mulch in your garden.

If you kill the blanket weed chemically, the dead algae will rot, a process that uses oxygen and releases carbon dioxide and ammonia which can harm your fish. 

The rule of thumb for pond filters says you should have a filter volume 1/10 the volume of the pond, and the pump should turn over 2X the volume of the pond each hour.   Your pond has a lot of fish for its volume  so I doubt that your filter can handle the amount of waste that these fish produce.  You can build a DIY filter with a barrel:

Looks like Shakaho has this - my mom was in town and I wasn’t online much.  But yes to the water changes and as much filtration as you can manage.  Those black marks look like ammonia burns healing, and water changes are the easiest way to manage that :)

The black marks are receding now, thanks for the advice. I reckon now it was caused by excess ammonia as said in the thread,
