Keep an eye on spot. Don't rush to treat it till your sure what it is. You can try MelaFix if its just a bruising or abrasion. Its helps to prevent infection & heal wounds. I had a CAE with red spot on mouth, got a little bigger, then just shrank this morning. It never had any inpairments swimming or eating. I never added anything to water and it just went away. *twirlysmiley*
