The one on the right is an Acan Enchinata, the one on the left is Acan Lord.
Your acan enchinata is eating your acan lord.
there's a possibility it's infected and the infection might spread. if you don't have the right tools to cut it, or if you rather not, I'd highly advise at least a iodine dip.what happens if i don't cut it off will that be a problem?
