From what I've seen of fin rot pictures online, there's usually more red or
irritation involved. This just looks like bits of the fin are disappearing.
Is that still fin rot? And if so, what's the best treatment?
Finally, should treatment be conducted apart from the other fish in the
tank, ie, should I try to quarentine this one, or will the others be okay
with the added medication?
TIA
