Fish were not doing well in CP

[jasonrusso]

Last Thursday I got a royal gramma and an orchid dottyback. I put them in a 10 gallon QT. I put in 50mg/gal of CP. They were still eating so I put in a dose of API GC. They ate the next day. They started slowing down for the week. Last night the gramma was lying down sideways on the bottom, I tapped him with the net handle and was kind of moved, so he wasn't dead but not well. The orchid was hiding behind the filter.

I put the carbon in the filter to remove the meds figuring they were having a reaction. This morning wasn't much better. I figured they were goners and had a bad day.

When I got home, they were both out swimming. Both readily ate some LRS nano. So at this point, I'm going to monitor them for another week. If all is well next Saturday, into the DT they go. I'm hesitant to add more medication. Hopefully they were healthy when I got them, and if not 7 days of CP and 1 course of GC was enough.

Fyi, this is the same "recipe" I have used for my last 7 fish without issue. Maybe these 2 are more sensitive? The last ones were clowns, firefish, foxface, angel, and tang.

It could be they were sensitive.

Have you changed how you were generating oxygen?

My guess is low oxygen based on combining meds. When you combine meds the surface needs very heavy agitation. Each additional med you add depletes the oxygen further.

I have the water level about an inch below the filter return so that agitates the water a bit. I also run a foam filter in the corner powered by an air pump.

How long has the QT been setup, that you are dosing CP into?

Also, I thought that the prazi in GC is only active for 4 days. This was 7 days later. Shouldn't the GC have dissipated?

Been empty since January. I filled it up 5 days before to get the heater set. I also added 12 bio max pellets into the filter that I keep in my DT sump for this reason.

The ammo badge never read anything over yellow.

It shouldn’t have gotten degraded that quickly then.

I would add a powerhead aimed up. You'd be surprised how much more oxygenation you get from it. I don't have any experience with CP. So I will let @Humblefish handle it from here.

What is "it?" I put the CP in after the fish. I like to see them eat at least once.

It = CP

CP can sometimes be rapidly degraded in a long-term QT that has been setup for awhile.

At this point I am just going to observe. They had at least one course of GC, and a week of CP that would have killed any swimmers. Neither had any cysts that would have dropped.

They both seem more active than they had all week and they were hungry.

Neither showed (or show) any obvious signs of illness (now, haha).
