Hi,
Is there a thread discussing and showing possible fish ailments?
I have a new pond, with new fish and one has been hovering on the bottom for about a week. He seems to have red patches around his gills - any help or advise please.
Also, I introduced 2 golden orf, we have a 2ft 6 waterfall and for 3 days they have been leaping from base of fall - onto the running water and swimming against the flow. One of them has disappeared altogether today

We originally filled our pond with tap water - could this be connected to the unwell fish?
Thank you in advance
Elemental.
