Possible fungus on goldfish
Hi, new here. I'm trying to get some advice about two of my goldfish (fantail and black Moor) I've had them for about a month and I recently had to move them to a temporary 24 litre tank after my 80litre tank cracked (toddlers and tanks don't mix...new tank arriving tomorrow ) since I have moved them 3 days ago, two of the 4 goldfish I own have developed small fluffy raised spots on their fins. I'm not sure what it is as I have never come across it before.
Any advise on what this could be and how to treat?
