What is this?

I'm very sorry for your loss.

I just finished fighting off a horrid bacterial disease in my 55 gallon. I lost a lot of fish but I'm not adding anymore for a while. I want to make sure this stuff is gone.

I would wait at least 2 weeks before adding any new fish. The disease/parasite could still be in the water.

I was just ich, and some of them developed fungus. I have the tank temperature at 88F, and I'm still treating, and there are no more sources for it to drop from, it won't be able to survive. I am still giving it a few days justs to be careful, but I am confident that it is gone, or cannot survive at all.

But the ich that did drop off the fish you had could still be in the water and could attach to fish. If it was me I would rather wait and be sure. I'm glad you are waiting a few days. I would give it at least a week.

I thought that once they dropped off, they became a cyst for 24 hours, then divided into 1024 new parasites, but need to attach to a fish within 24-48 hours? At the temperature my tank is, they can't even survive free swimming, let alone for a few days. Plus, I have the medication still going. I actually plan to add the fish in on Saturday, so just under a week.

They do hatch out in the substrate, but they may not all hatch at the same time. It could be over a period of several days.

That's why vacuuming the substrate helps a good bit, by removing the cysts that lay on the bottom.

The minimum should be 4 days after the last speck drops off, and that's if you don't have the heat and salt resistant Ich protozoan, as I did have. My tank was going 87 to 88 degrees, with .3% salinity, which is 3 level teaspoons per gallon.

I personally would go 10 days past the last visible speck.

Sorry about your loss, I lost several fish my self. Two days ago I did a massive water change 75% and started treatment with coppersafe and melafix. As of now the fish seem to be doing a lot beatter, my big Festivum is swiming around and looks a lot happier. He still has some white stuff on the tip of his fins butt overal looks better. I think they first got Ich and then Velvet since the white stuff looked less grainy the second time. Coppersafe treats for a full month so that should be enough time to kill the disease cycle. The tank is at 85 dgs, I keep you posted as the days go by...

Coppersafe and Melafix have done it, my fish are back to normal. I will wait two more weeks before adding carbon to the filters to get rid of the meds. Coppersafe treats for month so it should get rid of any left overs.
