Hi all
I have a Koi about 10"-12" in size today i noticed on his back he is getting red spots.I'm thinking stress due to water temps any help would be appreciated.He is now inside in a warmer qt tank with salt.

Got a pic? Red spots or red sores. Really a big difference. Ulcers usually come from within the fish and burst outward. Also although it is possible to get ulcers on their backs its not as common as bellies.
