Betta Fins Look Weird? Is He Sick?

HI guys! So I’ve had this male veiltale Betta for about 3 months now. He has been doing great in a 10 gal planted tank, heated and I use a sponge filter in his tank. I do weekly water changes of about 25-30%.

Today I noticed that his fins, his bottom fin in particular, look like they’re rolled up? He still eats and comes to the corner of his tank when he knows it’s time for food but I have noticed he is hiding more than usual. So what’s going on with him? Is he stressed or is he sick? What can I do to help him?

Thanks!

Edit: I also forgot I added new plants to his tank about a week ago. Could those be a part of the problem? I only use live plants in his tank

 

Live plants shouldn't cause fin issues unless they die, rot, and cause an ammonia spike. Rolled-up/clumping fins could be fin melt. What's your pH, ammonia, nitrite, nitrate, and temp?

 

It looks like a touch of fin rot. You could try daily 30% water changes, but if it gets any worse I'd treat with a broad spectrum antibiotic like Seachem NeoPlex.

Okay thank you I will try the daily wc! I changed his water today about 30% and he is already a bit more active than he has been and the fact that he still has a very good appetite makes me hopeful!

I don’t know the current parameters except temp is between 76-78. I was using the test stripes but they weren’t working well for me so when they ran out I order the apI master test kit and I’m waiting for it to arrive

I'd do the water changes as California L33 suggested, and keep the temperature at 78-79. 76 is a tad cold, especially for a betta recovering from fin rot. When you get the test kit, make sure ammonia and nitrites are 0 and keep nitrates below 20 at all times.
