please help new to fish keeping, inherited a pond with large fish in.
They have all stopped eating and have black marks on them. I have tested the water and its all fine, have treated them with Blagdon allround Pond Goldfish Treatment and they are still laying low in the water and doing nothing.
Could you give us a little more information please? Namely:
- Size of the pond in litres or UK gallons (if you don't know the capacity, then the physical size LxWxH and someone will be able to work it out for you ). - Could you post the actual results for ammonia, nitrite, nitrate and pH of the pond, as "fine" could mean anything - List of all of the inhabitants (including the actual number of each species) - Does the pond have a filter at all?
So for all the questions, but it helps us to help you
