Friend has oodinium outbreak

[RxMike]

I know a local reefer who made a bad judgement call. He accepted a zoster butterfly from someone he knows. Put fish in his 450gallon reef without QT. He is now going through an Oodinum outbreak. He lost 40 fish in 3 days. Looks like another 5 will die by tomorrow. Is there any hope for saving any fish?

Has about 25 left. He doesn't want to catch and treat thinks this will stress the fish more.

Is this going to result in 100 percent wipe out?

If this is oodinium, then most likely yes. He needs to catch, QT and treat all remaining fish ASAP. With either copper or Chloroquine phosphate. He can give the fish a f/w dip and/or formalin bath as temporary relief, but copper or CP is required for complete eradication.

I don't mean to sound callous but... if he's already lost 40 fish, why be concerned over "stressing" the other fish out? Better to be stressed than dead IMHO.

I went through an oodinium outbreak a couple years ago, ended up tearing my entire reef down to catch the 7 fish that were left, after losing 4 in 3 days time (which included the trio of Square Spot Anthias...grrr).

After catching the remaining fish, I QT'd for 3 months in a bare tank with pvc so the fish could hide. Used Quick Cure (Formalin and Malachite Green) during that 3 months (following the instructions on the label). 4 months later all fish were healthy and returned to the DT. No issue since that time.

If he hopes to save the fish that are left, he should move them to a Qt and start treating them asap.

Here's a good article from years ago (was updated last year):

From my experience, about 5% of fish can develop temporary resistance to oodinium. Unfortunately they are still carriers. The more normal course, sadly, is that all fish are lost.

Using "stress" as an excuse to not to quarantine all new fish or to treat fish with parasitic diseases has probably killed more fish than the parasites themselves. A slight exaggeration, of course, but basically true.

 

[enjetek]

wow. thats a lot of fish in 3 days. time to diagnose and treat fast...

 

[snorvich]

Amyloodinium kills quickly.

 

[enjetek]

ah yes. i was confusing it with ich - was at work . oh if you have that, good luck you better treat it f-a-s-t!

wow ...this is one devastating disease. He informed me that he lost another six fish. All of his fish are covered. They are breathing heavy. He is trying to catch them but is not successful. A tragedy
:headwally:

 

[enjetek]

Now we know why qts are important. . Yet ppl still don't use them....

 

[RxMike]

Yeah this is an example of what happens when we dont QT new additions that simply cannot be argued against. I cant imagine what the $$ sign attached to this tragedy is. No doubt it is a sad loss of fish but It is obviously a loss of some serious cash...

 

[Triggerfish]

wow..devastating event. how long was the BF in the other tank?

There is an issue with a non-therapeutic dose of copper masking oodinium. Possibly this was the issue.

 

[Triggerfish]

would like to hear more about the origin of the BF.
