Fin rot

[Gemstar]

Hi guys,

I am concerned about my betta fish as I think he may have fin rot. I think his fins have shrunk since I got him but it's hard to tell.

He only eats frozen/fresh blood worm and will not touch flakes or pellets.

Is there any signs that I should be looking out for?

Thanks!!

Finrot in aquarium fish - bacterial disease

Looks like it to me. Go get some medication Good luck

Tank size? Tank mates? Parameters?
Is it possible he caught it on something or someone is nipping at him?
Is it a clean cut or ragged?

It's a 10 gallon and he is in there on his own. I change 25% of the water every week so the parameters are fine.

I'll get some meds for fin rot just in case

Clean water does a lot for fin rot. I would up the pwc to 50% weekly and see if it helps any.
If you do meds, then I suggest starting with betta fix. If you use something else, you may need to dilute it a bit. Meds can damage a betta's labyrinth organ.
Bacterial fin rot is usually characterized by white edges on the fins.
