Question about ick

[b57378]

So I had a bunch of fish in a 50 liter tank and all of them died from ich
Except my pregnant mollie,she is still healthy and showing no signs of ich,why
Is this?how did she survive?

I heard that if the ich don't find a host within a certain amount of time
They will die so could this water be safe for her fry?

Your mollie might have ich, it just might be in her gills where you can't see it. Or she may just have a super strong immune system. Ich will die if it can't find a host, it will die at temperatures above 88 degrees, and it can't reproduce at temperatures above 86 degrees.

I think it takes about 10 days (might want to google that to get a more exact number) for ich to run its course and die if it doesn't find a host so I would think to determine if the water is safe for her fry would depend on how long it has been since the other fish died/when it first showed up in the tank.

How did you treat the ich outbreak? For me what worked was simply raising the temperature between 86-87 degrees. Three days after it disappeard I lowered the temperature back down to normal.

That's about all the information I have. I hope some of it helps you.

I didn't have time to treat it because all my fish were already very ill and died but thanks
