Hi everyone, quick question and observation hope you can help. My son noticed a small red spot right near the gill of the fish which looks like it can be from where it rubbed on something(possibly when I mistakenly added a Gold gourami and he chased it all over the place until I removed it and took it back), or a nip from other fish(which I doubt). Although it's acting as normal, eating etc... my concern is that it could be a disease of some sort. Any feed back or advice is appreciated please.
