Brook on Molly converted to SW??

[MamaP]

I just got a few black mollies to be my canary fish to verify Ich has been eliminated from my DT. Converted them to SW and they're in their own QT. Could they be susceptible to Brook? See pix attached. Does this look like Brook? Only one of them looks like this. Started treating GC in water and in food with Focus today once I saw this and a long, stringy, white poop in their tank. If this is Brook, will the GC in water and food kill it?

Could be brook, but they are also prone to fungal infections that sometimes carry over from being in FW. How long have they been in your tank?

Since Monday.

Since Monday.

SW should have killed any FW fungus by now. Is just one of the mollies look whitish or all of them?

Only the one.

Only the one.

I'd let it ride for now. They should all hit for brook if it is present in the water. And let the white stringy poop go for right now as well. I've noticed with mollies it sometimes goes away on it's own after a week or two in SW. Either the SW is causing intestinal irritation or it finally kills the freshwater worms living inside their intestines.

So should I not continue the GC then?

Discontinue that for now. While you're waiting to see if the other black mollies hit for Brook, see if the white stringy poop persists or goes away on it's own.

Ok. Thank you so much for all your advice! I appreciate it!;Cat
