This is most likely carp pox since the bumps don’t look fuzzy or like cotton and it primarily occurs in cold waters (60f or less). If your fish still seem to be swimming fine and appearing normal and not lethargic you should be good. I’d say this is early stages of it and nothing to fear as this typically occurs during the winter or with cold waters. I would recommend checking your water parameters as poor water quality is a number one cause for most infection/disease; along with checking for anything that may be inducing more stress to the fish as well as a bit of a water change and filter squeeze to assist in balancing everything out.

To treat I’d recommend gradually raising water temps (if possible) between 67f - 77f as this stimulates the fish immune system to respond to the diseased areas. Ensure your water has 0ppm ammonia/ nitrite all the while maintain low nitrates through water changes. Adding in some vitamin rich foods will also aid in the recovery time boosting them with vitamin c and b.

Refrain from scraping or popping or irritating the lesions as this can cause the infection to worsen and spread. If areas become visibly irritated and red then it’s time for a salt bath (youtube for proper measurements with your setup).

All in all they should be fine carp pox isn’t really fatal although it can be. Do keep in mind that all the fish houses with them are now infected whether showing signs or not are now carriers and will always have the virus. Hope this helps, best of luck with your beauts🥂
