Well good news. He’s growing back that fin nicely. I thought it wouldn’t since there was nothing left visibly.
I ended up taking him out of the 350g and putting him alone in a 75g. Since, his color has turned from very dark to a beautiful gold like I always thought would be the coloration of Cubans. Maybe grown some. I need to measure. But his confidence is way up and feeding great on cut fish and pellets.
I’ll get some pics soon
