What the heck is this? Fish keep dying!

[Bunkerbean]

So I had a PB and he got some ich. I bought Seachem Metronidazole to get rid of it. I have 180 gallon tank and my parameters were pretty good. For some reason my PH stays 7.8. I had nitrates at 40. So i did 65 gallon water change. Prior to the water change My PB, Pearlscale and Flame angel all passed within 24 hours of each other. While at the Fire station my wife turned off the AC and the tank was 85.5 F this morning. Not sure if this is what the Yellow and clowns are suffering from. I am going to recheck parameters, but I am trying to figure out what could be going on.

So my parameters are all 0 and ph is still 7.8

looks like Brooklynella to me

 

[Bunkerbean]

How do I fix it?

The first picture of the clown does look like brook, but the second plus how fast the fish are dying makes me think velvet. You need to get the remaining fish into a hospital tank ASAP, and treat for velvet. The display needs to remain fishless for 10-12 weeks to ensure that all remaining parasites in the display have died off, and from now on I hope you quarantine all new arrivals.

 

[Bunkerbean]

Ok how do I treat velvet?

 

[Bunkerbean]

Is formalin good to get.

 

[Rea17]

Cupramine is the best velvet treatment IMO, formalin is a last resort med as it is fairly nasty stuff. Formalin is the best brook treatment as far as I know, but not a good thing to keep in the fish medicine cabinet as it doesn't store well. If you need some, get it fresh.

Ok. So my neighbor has a 65 gallon tank I am going to setup as an emergency hospital tank for the next 10-12 weeks. It won't be cycled so should I do weekly water changes?

There's quite a few stickies at the top of this forum that cover all your questions.. It IMO is better to just have the answer instead of waiting for it.. Plus it's stickied for a reason meaning it works. You can get answers that aren't 100% true from the masses and the stickies will wade that out.. Good luck

 

[Bunkerbean]

Thank you. Read thru them still have questions.

Use a bottled bacteria such as instant ocean bio spira, or if you have any ceramic or plastic filter media in the current display tank and use in the qt. An ammonia alert badge is a must, most ammonia test kits give false readings with copper.

 

[Bunkerbean]

Ok thank you. Since this is FOWLR can I just drain the tank and start over rather than waiting the 12 weeks. I am not opposed to waiting, but I thought of moving my tank to a new location in the house.

 

[Mrscribbled]

I hear ya, I have removed livestock then bleach the display, drain, air dry, then restart with great success

 

[Bunkerbean]

Excellent. Does concentration of bleach matter?

 

[Mrscribbled]

1 cup per gallon to have full kill.

 

[Bunkerbean]

I will have to do the rock and everything correct.

 

[Mrscribbled]

Yes

 

[Mrscribbled]

Replace sand bed with new fresh sand

 

[Bunkerbean]

Ok will do..
