Hello I have pond bass and one of them has a nasty red bump on his lower Lip. I cant real ID it... I added salt gave him fungus stuff along with fingot meds (all in one kinda tablet) But i dont know what this is. Some one said it might have been from running into a Wall but when we added him it wasnt as bad. light pink now its getting darker in color and allmost looks like a hole. But it hasnt healed in months So i have no idea. Anyhelp would be nice. Sorry for the pic Best i can take in his H Tank.
