Betta boop looks huge! Is it possible that she’s a “king” female?
I honestly don’t know! I got her from a chain pet store, she’s a GloFish, and fluoresces under higher-frequency lights (from blue on up). I have no idea what stock the company started out with when breeding them, but it would stand to reason that they would select a light-colored line.
If you “think away” her fluorescence, she looks quite a bit like this picture of a “pale” colored Cambodian b. splendens male, but it’s not described as “king” and I couldn’t find another picture of a betta of similar coloration.
She was somewhat smaller when I got her in November, and I’ve been feeding her frozen/thawed foods in the morning and a few pellets most afternoons, soaked in VitaChem. I make her jump for her food, so that she can keep in good body condition.
She’s my first betta, so I don’t have any experience for comparison.
