Major fish kill Corpus Christi Public Aquarium

[Mike Ordner]

The Texas State Aquarium was using Dylox to treat for flukes and killed nearly all the fish in two main displays. Sad day for the city. Anyone out there know about using this chemical for treating marine aquariums?

So sad...Dylox is extremely hard on fish. The only reason I can think that they used it instead of Prazi or Levimasole is cost. Dylox was recommended to me when I was dealing with a fluke species that can be resistant to Prazi.

Sad. Dylox can be incredibly harsh.

I have never understood why places still use Dylox with everything else that's available... This is the third or fourth place in the last year to kill off all tank inhabitants using Dylox

From what I read this was a persistent parasite, so maybe they did try other things before this. I don't know anyone who still works there so I do not have any first-hand information, only what I read in the media.

I dealt with a very stubborn species of flukes a couple of years ago that nothing would eradicate. It took about a year for me to finally get rid of it. After much research I found a research paper in which some Japenese researchers had found that neobenedenia girellae can be resistant to Prazi. My local marine science center confirmed I was dealing with it.
Hopefully they can find out what they are dealing with...you gotta know your enemy before you can beat them:uzi:

Another reason why you should never treat in the main display and do rigorous quarantine - especially if your fish go into a large or even huge tank.

But flukes being flatworms - can they survive freshwater dips or hyposalinity? What about formalin dips?

I am certain that they have a quarantine system in place. People do make mistakes and they made a costly one.

Monogeans can be host site specific. Studies showed the species that prefer the gills can dig in deeper into the folds of the laminae to hide from treatment.
I did eventually have luck eradicating with a series of formalin dips.

Just looked through my copy of Bassleer for a medication that kills crustacean parasites and it recommends Trichlorfon (Dylox). But there it also states that Trichlorfon is toxic for sharks and some other types of fish. It further states that all fish need to be closely monitored during the treatment and the water being exchanged at the first sign of the fish feeling uneasy.
So they should never have used it in tanks with sharks to begin with.

Very sad. Shows that even the experts face great challenges.

So they are suggesting that they had "film processing" powder sitting in the same room as the fish meds? Seems like a real poor decision if that's the case. Not sure I believe this, but this is the story
