Potter Angelfish and Copper

[Pneumatic_Addict]

Afternoon All,

I know certain Pygmy Angels are hyper-sensitive to copper. Just wondering if Potter’s made that list? Or anyone’s personal experience with QT’ing?

I have CP and Cupramine on hand. Either better suited? Picking up one today, gunna start dosing in the next week or so.

Afternoon All,

Centropyge angels are sensitive to ionic copper. Copper/citric acid is the most toxic to them, but Cupramine also has some reported issues. Amine-based chelated copper products are much safer - Coppersafe or Copper Power are what I recommend. Chloroquine is not without its own risks. I would not dose it higher than 12 ppm and monitor the ammonia level after treatment. Then, it has also been difficult to source chloroquine lately.

As a side note - I didn't know any Potter's angels were in the trade right now, with Hawaii closed to all collecting. I think they range to Johnston Atoll, but I didn't know anyone was collecting there....and then, they would have to pass through Hawaii and I didn't know that was allowed either. I know some were captive raised back in 2016, but I thought that was a "one off".

They’re not. Local guy breaking down his tank, was just quick on the draw PM’ing him.

I meant CP = Copper Power. I haven’t used Chloroquine in so long I forgot it was the preferred acronym.

Never known a way to measure Chloroquine once it’s dosed, so I’ve pretty well abandoned it. Is there a way? I have some in my “Random bin” I could dig out.

If this potter’s has been a healthy fish in his tank, for the past 2 years I would presume, why would you subject it to copper? Put it in an observation tank for 4-8 weeks. These are hard enough to keep thriving and sounds like this is a good one. Or does this have ich that you can see?

I see - yes, Copper Power is o.k. on Centropyge, you just need a good test kit (Hanna Checker HR is the best) to be sure that you hit the target dosage of 2 to 2.5 ppm

With it being a long term captive, that *could* reduce the risk for quarantine, but there is still the risk that the Potter's has "been with" every other fish this person put in their tank, and what if they had added some sketchy fish in the past few months? Unlikely since they are taking the tank down, but you'll want to ask. Then, you might be able to get away with an observational, 45 day isolation period.

I agree. Nothing goes into my display without sitting in my observation tank for at least 8 weeks. But my fish usually sit at the LFS for a month before I take them home. Not 100% risk free but I’m ok with it. I do hit them with prazi though.

Tcook - I lost enough the last time I trusted someone’s “well established” fish, will never happen again.

Jay - Hannah is in the mix. Appreciate the info

It get it. Been there. The whole fallow QT process is not fun.

I would recommend coppersafe. My personal and professional opinion. It’s very soft on this fish and even if you go slightly over, it won’t hurt anything.
