Hey! : ) My betta has continued to grow, but I'm still not 100% sure what he is!! He was labeled as an hm at Petsmart, but I don't trust that. I'm not sure how much more his fins are going to grow (he's less than 2 inches long).
Him a few weeks ago:
His name is Caravaggio!
His colors haven't changed as much as it looks like in the pic. The aquarium light just makes it different.
