Curled Betta Fins?

Hello! I’ve had my butterfly betta Neptune for four months now. When I got him his fins were straight, but as he grew they started to curl. Pretty much all the tips of his fins are curled now and I have no idea why. He lives in a heated, filtered, planted 5.5 gallon tank with my mystery snail Eclipse. I feed him betta pellets and frozen brine shrimp and do 30% water changes every week. I’m worried that it could be fin rot or something. Does anyone know what could be causing it?

Any other fish in the tank? If so it might make him feel like not enough room for him to grow his fins. I'm sure other will help as I never had good luck with bettas or know much about them.

 

It's a pretty common thing that occurs for bettas. There are many possible causes for fin curling for bettas as we don't exactly know what causes it. Once the rays are bent, they most likely won't be able to go back straight.

It's harmless and is just going to be a cosmetic issue. Just continue to keep his water clean. Some people say that keeping him near sunlight will fix it because of a vitamin deficiency.

I'm not sure you've correctly identified your betta.
Here's a link to a good site for types of them.

I'm not versed with bettas either, but I'll just say I think he looks nice like that! Doesn't look like rot, in fact he looks more filled out now

 

He looks like a rosetail betta. Rosetails often have finnage that curls at the ends. The only thing I would caution you on is to keep an eye on his behavior. In some bettas this curling can cause severe pain. Make sure he is appropriately active and had a good appetite. If he gets to where they are causing him trouble you can trim the curls for him UNDER SEDATION. Because of course that would also be painful.

Edit: he’s really very beautiful

Sorry for the super late reply haha, but you’re right! He was labeled as a premium butterfly betta at the pet store so I figured that’s what he was. I’m guessing he’s actually a rosetail betta, which makes me sad knowing the complications they tend to have But thank you!

Thank you, and sorry for the super late reply! You’re right about him being a rosetail haha, he was labeled as a premium butterfly betta at the pet store so I didn’t look into it. His fins are still the same, but he swims around his tank a lot, he’s a voracious eater, and makes bubble nests regularly, so I think he’s happy and healthy! Thank you!
