Betta Problem

Hey,

I got a Betta the other day and when I put him in his new tank I noticed a little bit of white on his dorsal fin, but couldn't see it well enough to know if it was just colouring or if there was something wrong. Have had a better look today, and I would say there is something wrong. I thought maybe whitespot, but I have managed to get a photo of it and it looks different on the camera to what I can see. Any ideas? Also suggestions of what to use to sort it out.

Thanks

Can't tell in the pic, is it fluffy looking.

Not fluffy, just blobbish if that makes sense.

If the fish isn't flicking and rubbing I would treat it as bacterial.
Water stats would be good.

Just doing them now - just knocked half the bloody Nitrate down my leg as the door just went!! I am due to do a partical change too so readings could slightly change.

Ammonia - 0ppm
Nitrite - 0ppm
Nirate - 10ppm
PH - 7.6

I'll sort something out for bacterial, just so that I have it if that's the case, as he deifnately isn't rubbing or anything and he has a big piece of bogwood to do that on if that's what he wanted.

Thanks for helping me out

Been back to the place I had bought him from and described what was on him, and they also said it sounds bacterial, so I shall treat him that way.

Thanks for all your help
