That female is gorgeous! I can kinda see the similarities between her and Athena's tails. Wow I hope they get more DTCTs out because they're really pretty! I wouldn't mind having 1 or 2 more Athena's zooming around ;)
Now that you mention MArine's anal fin, I've started to enjoy it a lot more now xD It's cool how it's half black, half blue/white, and a diagonal split.
His dorsal fin is still bothering me though. IT's barely spread out, and usually always clamped. Also, the blackened curling at the end does not look good D: Are you sure it's just the natural colouration? You're probably right, cause if it was finrot, it would've been eaten away by now, since I noticed it quite a while ago.
Marine's a smart little fishy! He's honestly just like Dusk. He never flares when I hold up a mirror, but as soon as I put a betta tank next to his, he's flaring all over the place.
And thanks BettaLover
