How beautiful!!! I have a female EE, Mist, with the same coloring. Did you get him from a breeder?
My breeder's label for Mist reads "HM PK Dumbo". I'm not sure how you can have a HM PK. I'd love to breed for this color of ours, but I'm not sure having an EE in the mix would be a good idea. OT a bit, are certain colors genetically associated with fin type?
4 bettas: Butch, 3-year-old violet male PK EE & 3 girls in a 30 gal sorority. I do not name the girls anymore! 1/2 of them die within a month.
30 gal: 9 Oto cats, 4 Ocellifer cats. Inverts: Cherry shrimp & 2 assasin snails.
10 gal.: Butch, his 5 oto cats, 3 assasin snails, and a few snails the assassins haven't caught.
