I will be receiving a halfmoon I bought on AquaBid this week. He is 3 months old. I was wondering if his fins are still growing or is his fins already at it's maximum potential at 3 months old?

It really depends on the genetics of the fish when the fins stop growing. My halfmoons and superdeltas reach their full finnage length at around 6-8 months old....depending on when they are jarred. Other halfmoons I have had in the past as pets may grow to an excessive length and weight that makes it difficult for the fish to swim and cause the fins to collapse or prone to fin rot.
