Cory Diagnosis

Hi all

I'd be appreciative if people could take a look at this growth on my cory's tail. He has another one on his (anal?) fin that you can't really see in this shot.

I can't get a good look at it (it doesn't look worm like. but it doesn't look fungus like) because the little darling moves too fast, and I can't get a good photograph of him either - I'll borrow a better camera tomorrow. He must have had this for about a month now and it is getting bigger slowly.

Any thoughts appreciated

It looks like an external bacterial infection to me, often related to finrot or fungus, use Primafix to treat it(treats external and internal bacterial infections plus fungal ones) ;
