How to eradicate Oodinium

[Rennan Serrano]

Hello Fellow Reefers,

I hope that everybody is doing well.

Recently i have a disaster in my display tank. By introducing fish without quarantine i've contracted Amyloodinium ocellatum.

At first I saw that some fish were getting covered by a dust like ich (very thin and numerous) and swimming against powerhead during 2 days. After that i've lost 80% of my fish within 72 Hours them 10% more in 96 hours and now only some clownfish are struggling to live (i am getting them out to a QT with cooper but not much hope on that because they are really affected).

Therefore i'm planning to get all my fish out of the tank and leave for a while (120 days) without any kind of fish.

My main concern now is to adress a proper action plan in order to eradicate this parasite (and others such as Ick) out of my DT to host future quarantined fish without reintroducing this parasites.

Regarding the action plan to eradicate this diseases from my DT could you please comment on the best way to adress it? So far i've planned:

- No fish for 120 days
- Keep inverts and corals in my DT (or should be better to take them out as well?)
- UV Sterilizer On from now on and forever
- Dosing Microbe-Lift Herbnata in the DT without fish (or there is something better since no fish will be there?)

I hope to have your comments, specially from people who lived this terror and had a happy ending (lol).

Regards,
Rennan

Give the clowns a freshwater dip, it might help buy you time to get them into QT. Followed by a rally bath if you have it, but if not definitely the fresh water dip.

The display will need to be fallow for 76 days if you want to be sure both velvet and ich are gone. You don't need to do anything else besides run fishless for 76 days to eradicate the parasite from your DT.

And of course QT all fish and corals moving forward to prevent reinfection.

Velvet sucks...sorry that you lost your fish...it's the single biggest reason I quarantine everything these days.

Last year I received a small Atlantic blue tang in error (the vendor mixed up my order with someone else) that I was not expecting so I did not have a QT setup and cycled. I added the fish directly to my display (I've been in the hobby about 25 years so I knew better...stupid mistake). Long story short a few weeks later I lost all of my fish in a similar episode.

As mentioned above...you just need to leave the DT fallow for a few months. Since the tang incident I've been using chloroquine phosphate as part of my quarantine process now to hopefully prevent ever having that experience again.

Hello

If i misslead the conclusion of my problem and it could be Brooklynella instead of Velvelt.

Will the same action plan (no fish for at least 76) eradicate this parasite as well or another treatment is required?

Last question: When you say "DT need to be fallow for 76 days" it means no fish only or no kind of life whatsoever (corals, inverts, etc).

Rennan

Corals and inverts are fine, just no fish.

Is there a reason you suspect brook? The symptoms you described were spot-on for velvet. Do you have any pictures of the fish?

Some of the clownfish got with a heavy white duvet on them at the end.

I manage to take a shot from one clownfish that is still living and not so attacked as the others.

I suspect that i might have contracted both since one of my clownfish that died had this white cloak hanging out of his tail.

I'm really confuse because i saw fish at beginning with clear symptons from ictium (big spots), them the thin dust that looks like velvet and some with a heavy cloak that could look like brook.

This is how you would treat for brook: https://www.reef2reef.com/threads/brooklynella.247938/

A 5 min FW dip + acriflavine or formalin bath + 30 days in copper will work either way.

The only thing I would do differently is dose metro (for 10 days) in conjunction with copper if you suspected brook.

Thanks!

But for DT is the same therament as the others? leave fishless for a while or need to do anything else?

Leave the DT fallow for at least 6 weeks; 76 days would be better.

If anybody might still be following this thread, do these 3 types or parasites burrow in sand beds like hibernating until a host comes along?

Hello MintMocha,

Yes they do have a cyst phase where they will stay in sandbed, rocks but if there is no host they won't be able to complete their cycle and therefore collapse over time.

This is why it is important to have the fallow period

Rennan

Thank you Rennan!

I’ve read many forums and sources for the fallow period and the most common I see is 76 days. I don’t mind waiting shorter or longer! I want them out and never again not using my QT tank. Something I bet we’ve all made our first mistakes with lol

Ich - cryptocaryon irritans requires a fallow period of 76 days, velvet - amyloodinium ocellatum has a recommended fallow period of at least 6 weeks.

If you are unsure which you’ve had, specifically, I’d opt for the longer period - to be safe.

It is also recommended to periodically stir the substrate to reduce anaerobic areas that the encysted parasites could remain dormant longer than the typical fallow period.
