Damaged dorsal fin?

[PNWBettas]

I have a little plakat betta from philam and he’s got something going on with his dorsal fin. My theory is it’s from the floating log I had in his tank since he wasn’t the most careful around it, but I just want to get a second opinion.

I don’t think it’s fin rot since the rest of him fins look fine, and I have 2 other betta in this tank (it’s a 20 gal divided into 3 sections) and all their fins are healthy.

I also don’t test this tank water too offten since it’s so under stocked and it’s cycled, but I did once I saw this initially and removed the log.

Parameters are:
0 ammonia
0 nitrite
0 nitrate
7.6 ph

Since this tank has a higher ph I’m planning to add some tannins. I’m thinking of trying roobios tea.

Otherwise he’s swimming around active, eating normally and has no other physical ailments. And other thoughts?

Really cool lookin' fish!

I would just keep the water clean against possible infection and keep an eye on that fin myself.

That’s probably from hitting it too often in your tank. Bettas like to go through holes that they think they could fit in and maybe he bent his dorsal. As long as he’s fine and eating good and no lethargic symptoms or discoloration, I’d think he’s all good. By the way, idk how he became like a blue marble lol but I had a female just like him. I’m sure he’s still marbling on you and he’ll become a red blue galaxy like his bros!

Yeah I'm mad I didn't notice it sooner, but I can just do larger water changes for now to make sure it heals up.

Yeah it’s likely from the floating log, that explains why it’s only the top fin. He’s also just as active as ever and eats well so I’m not too worried about it. And yes his coloring is super unique! He does have a few orangish scales on the top of his body which may come through more as he continues to grow
