Here's the latest from Callisto. He's hard to photograph and the lighting in his tank is awful, so this is him in sunlight (without his irids). His irids make up a huge amount of how he looks though, so he shimmers of of blue and green on top of his black\red base. He has some white\clear finnage too, which is hard to see in the photo. He is actually a double tail, but it's so full and bushy you can't see the tail split. He's still a very calm betta, and still a sweetheart.
