View Full Version : Getting rid of velvet?

I had velvet appear in my tank and kill a few fish overnight.

Currently what I have done is to remove all the fish from my tank, leaving corals, snails and other inverts with the rock inside.

Surviving fish are in a qt tank, and include chloroquine intolerant fish.

I'm intending to fallow the tank for up to 3 months to get rid of the velvet parasite and just in case ich found its way in as well.

However, how do I treat the surviving fish in qt? Is copper up to 0.5ppm for 4 weeks the only way to ensure I can start my tank off clean again?

72 days fallow for the dt is preffered.

6 weeks should actually be enough to rid a system of Amyloodinium (velvet).
The 72 days are for Cryptocaryon.

Exactly.

3 months is 90 days :) I'm playing it safe here, since I'm already doing 6 weeks, what's another few more weeks?

The question still is, is copper my only option to make sure the remaining fish are clean? I can't use chloroquine as I have a Bodanius that is sensitive to it.

Anyone? Do I need to copper the surviving fish to ensure I'm clear of velvet? They have not shown any signs of it in the past 2 weeks since I moved them to the qt and started fallow on the dt

Unless you got a copper tolerant strain it should work.
You may consider separating the wrasse for copper treatment and treating the rest of the fish with Chloroquine.

Thank you - unfortunately I only have 1 qt tank (spare 60 gallon from an old setup) and nothing that can hold the hogfish for 3-4 weeks while the other fish go through chloroquine.
