Hello!
I recently picked up a new Betta, he seemed very active in the shop, good colour, and bright eyes. He's been very active in his new tank. He was incredibly aggressive towards a nerite snail resident when he first went in, but thankfully he ignores him now. Shortly after I got him home I noticed some transulscent sections on his tail fin and some dark colouration along the tip.

I've been keeping an eye on it and while the tail fin seems to be generally ok, one small hole seems to have appeared (can't be seen below, light is off at the moment), but more worrying is the dorsal fin now seems to be clumped together at the tip.


Should I be worried about his fins? He's quite small, so quite young I would guess.
Would you consider treating him? Or might he start to improve after a few weeks in my tank? This tank is long established, 60L, been running for over 3 years, Am/Ni/Na are 0/0/20 as tap water here comes out at 30 nitrates. It's heavily planted, filtered with a baffle to lower the flow, and heated to 79F.
Thanks for taking a look.
