2 Fish Wipeouts

[Stoatee]

So I had what I thought was brooks 8 weeks ago pulled the fish out managed to save one in quarantine did both copper and flukes treatment. Had about 6 fish all died within a week other than the 1 clown. I bought another clown to pair in quarantine and all went well had them together for 4 weeks. Added them back to the main display that had no fish in for 8 weeks just corals and inverts. The original clown died in 24 hours and the new one is 72 hours. What is wrong with this tank? Surely brooks couldn’t survive for 8 weeks and kill fish again that quickly? I have posted my water parameters along with my test result from my water that I sent off after the first wipeout. There is no ammonia, salinity at 1.024 and the temp is 25 degrees.

Have any pictures of the fish? Sounds like it could be velvet.

How long has this tank been up and running?

I have pictures of some from the 1st wipe out.

The tank has been going around 5 months

Copper isn't the best treatment for brook but I would have thought you to have seen brook on the fish before they died.

Could there have been a salinity swing between the two tanks?

 

[ReefCheef]

Are you using RODI to make the saltwater?

They were dripped in like normal and were fine to start

Yes we have an RODI machine but we did that water test just to make sure nothing was in the water that was crazy harmful

But was the difference in salinity between the two tanks far off? If they were, fish need quite a bit of time to acclimate (i.e. days). That is the only thing I can think of. Unless the fish had visible signs of something wrong.

When we posted on here people though brooks was what it was and to treat with copper it did seem to work the surviving fish was in the quarantine tank for a good 4 weeks swimming around eating and happy then died in the first 24 hours of the new tank

just checked and the salinity in the quarantine is 1.025 so only a 0.001 difference

So from the results I have posted and explanation of what happened there is no one who knows what is happening? Looks like it will be a tank tear down

 

[I never finish anythi]

Clowns tail looks a little beat up . Unless it's just the pic .

A tear down isn’t needed.

I was in your shoes once a couple years ago. After a non QT introduction our clowns broke out in what we thought was brook. Everyone got moved to QT. The clowns passed while in QT, but some other fish survived. We fallowed for the recommended 6 weeks +1 week.

Introduced the fish back in and started losing fish within a few days. This time velvet seemed to be the culprit. Especially considering how quickly the fish were dying.

QT’d fish and fallowed for 76 days. Careful of cross contamination and had no coral/inverts introduced to DT.

Got velvet again.

90 days fallow. Seemed to do the trick, and a lesson learned on quarantining fish.

I’d recommend a longer fallow.

90 days fallow? We have had someone message us also saying to try 1 more fish to make sure there wasn’t something wrong with the clowns before. We could try 90 days fallow but just thought how quickly they died after going in that it couldn’t be to do with the same as last time and why we thought it might of been a water issue that we can’t put our figure on

Copper does not treat brook... I believe it can suppress it.. not cure.

What does treat it? We had them in water without copper but instead a treatment for flukes for 4 weeks after 4 weeks in copper and the clown that survived stayed in good health and eating and the new clown seems to also be okay
