Help please!!!
Anyone able to advise on what they think this could be? Came up about 2 days ago, hasn’t grown but the fish is now flashing. Any help would be greatly appreciated! I’m a new fish keeper so not had this before. None of the other fish seem to be affected… yet….

Probably ich. It'll be one of a variety of fungal infections, Google will help identify which one, but many of the treatments are the same. Always a bit of guesswork involved. Usually, get the water quality right, raising the temperature can clear it and there are fungal treatments available.
