He's beautiful! So he's still 10 inches long? Did you have to treat his hole in the head with medication or did it heal on its own just by removing the females and reducing stress?
Your male looks so "mature" compared to mine. Mine is 9 inches and I've had him for 1½ year, but he's still baby-faced. He still has that "slender and athletic" body shape that juveniles have and hasn't bulked up yet. But to compensate, he has the most orange tail I have ever seen on a green terror! I say he has an orange tail with a blue band rather than a blue tail with an orange band. lol
I wonder if he'll eventually get that "mature" look that yours has or if he'll just keep this "big baby" look he has going on.
