Who Gives A Fish Forums

Just got a new Betta, trying to figure out the type. Thinking it might be a halfmoon or rosetail, but not entirely sure. I've attached a picture, but unfortunately, I couldn't catch him with his tail fully flared.

I'd lean towards a rosetail, delta, or possibly a halfmoon. There's a helpful link I came across with pictures showcasing different types of betta tails - https://www.itsafishthing.com/types-of-betta-fish/. Hopefully that helps you narrow it down.

Thanks for the link, really interesting read. I managed to get a few more shots with the tail almost fully flared, but as soon as I'm near him he starts swimming around like crazy. Guess I'll just have to keep trying to catch the perfect pic.

I'd say he's likely an OHM, or possibly an RT, but we really need a clear shot of him flaring to be sure. A video of him flaring would be great too - either way, we'll get a better idea of what we're looking at.

Don't think the ends of his tail are curled enough for a rosetail. I'm leaning towards halfmoon, personally.

I'd say delta or halfmoon's a possibility. If you can manage a video, screenshot the best flared pose, might give a clearer idea.

Try putting a mirror in front of him, see if that triggers a flare. If his fins spread to 180 degrees, I'd say halfmoon, under that it's likely a delta tail, and over 180, well then it's beyond halfmoon. Either way, he's got beautiful colour.
