Hi,
My first sick fish experience.
One of my 2 new Peppered Cory's (Eric and Ernie) had a white marking (looked like scar tissue) on his fin the day I bought him, but only noticed it late that night, following morning, there was cotton wool like fungus all over his fin, so off I went to LFS.
They appologised, it should not have left the shop, but he missed it, he told me to return it and he'd swap it.
I decided instead to try and treat it as I'll have to get used to treating sick fish at some point, so got fungus/finrot stuff and treated for the 3 days it said to, following instructions to the letter (including removing carbon filter).
Now 2 days later, the fungus is still there, the fin looks better but the cotton bud is still there, should it have dissapeared or does the treatment kill the fungus but it takes time to drop off?
Do I need to continue treatment?
I can still take him back to LFS, but I've already grown attached to him and he seems fine, he's always busy, not rubbing it or flinching when it gets knocked and boy is he feeding
If it helps water stats are:
Ammonia 0 - Nitrite 0 - Nitrate 25 - PH 7.2 - GH 10 - KH 6
I'd appreciate your help as to what I should expect to see or what I should be doing, as would Eric.
