The other day about a week ago while cleaning out tanks i noticed that my prized male has a weird bump on the bottom of his belly.It looks like if he ate something but i know that is not what it is. When i first saw it thats what i thought so i gave him time to pass it and i found stool and the bump disappeared. Then about two days ago the same bump. Its on his belly about five inches past his head. All his functions are still doing perfect. Nothing is different besides his bump.
