Kole tang dieing

[Gui Paim]

Yellow eye kole tang had ich about a week ago. Figured it was due to stress from me adding a foxface. The tang got better within a couple of days and no longer showed an symptoms of stress or ich. Fed him yesterday and he ate like a pig.

Woke up this morning and he looked like this:

I did a freshwater dip on him for about 3 minutes and it seemed to atleast make him a little more comfortable.

Nevermind guys, guess i was to late. He just passed away.

I'm sorry you lost your fish.

If I had to guess, the Ich didn't clear up, it finished feeding and dropped off to reproduce. This new attack was the massive amounts of new parasites hatching.

Are you going to try and take your tank fallow to clear the Ich out of it?

 

[drawman]

Sorry for your loss that sucks. I would do what Brew suggested and treat the rest of the fish and let the tank go fallow.

I third the fallow ... that's the only way to get rid of it.

I know it sucks to remove all your fish and QT. I had to do it and removed all my rock from my 180 to catch them, what a pain in the butt. But I don't like to lose fish and I want to be sure there isn't something lurking in my system that could spring up at any time and kill my 1,000$ worth of fishes.

That has all the sound and appearance of velvet to me. I'm guessing the foxface brought it in.

I would treat with copper the remaining fish in that tank and run the tank they were in fallow for 76 days.

I agree with this now that I'm on my computer and not my phone. This looks much more like Velvet than Ich to me.

 

[melypr1985]

I agree... it looks like it could have been velvet. Fallow in the display for 76 days and copper for the rest for 30 days. good luck!

I was afraid for that. Ill have to go invest in a qt tank. Going to be a pain in the butt to get all of these fish out. Can this just be a 40 gallon bin or does it have to be a glass tank?

 

[Gui Paim]

Also, does the qt have to be up and running for a little while?

If it is food safe or made of PVC it is probably fine to use. Just avoid the soft plastic containers.

As long as you are prepared to do water changes frequently to avoid ammonia build up, then you should be fine. You'll need a powerfilter for the container (whatever you end up using), heater and PVC elbows for hiding in. A small powerhead or air stone should help out with oxygenating the water as well.

I agree this is likely velvet. More info here: https://www.reef2reef.com/threads/velvet-amyloodinium-ocellatum.217570/

@Humblefish

If velvet is a dinoflagellate and can obtain food via photosynthesis, does removing all fish even for 12 weeks really get rid of them? Or do they actually need a host to survive?

 

[Brew12]

To the best of my knowledge, Bower's study in 1987 is still the most comprehensive look at the life cycle of velvet as it applies to marine aquariums.

According to Bower (1987) dinospores can usually live for 7-8 days without finding a host and are infective for 6, remaining alive and infective even longer at lower temperatures. She recounts that though most emerge from encystation within 5 days and survive another 7 to 9 days, some dinospores were present in their test tanks (at 75-80 F.) some 37 days later.

6 weeks fallow will eliminate velvet from a tank. Because even though tomonts & dinospores can survive for some time on photosynthesis alone, they cannot survive indefinitely without fish flesh to feed upon.

Would the process be accelerated by raising the tank's temperature to the maximum that the remaining occupants (i'm assuming inverts, including corals) could handle longterm?
