Help!

I just came home and found my centropyge bispinosa flat against the sand. It doesn’t show any signs of desease at all & ate perfectly fine yesterday. The fish has been in my tank for 1,5month now & always was happy. Other fish look happy aswell.

I caught it & put it in an acclimating box.
Now the fish is just hovering in place but doesn’t wanna eat & breaths quite fast.

& it still looks quite weak :(

Off the top i do not see any signs of aggression. It is possible the fish ran into object but other factors, change in temperature, salinity , ph and a spike

Sadly i have no idea, my salinity & temp is perfectly fine atm. All i can do rn is measure my PH but that wont show any previous spikes..

Did you add anything recently? How long have you had the fish. A fish lying on its side breathing fast suggests a gill problem - like a disease/parasite. Especially if none of the other fish are affected.

Didn’t add anything in the recent 4 weeks when it comes to fish or corals.
Last week i have been adding live phytoplankton but that’s about it.

There is no way to tell for certain, but this species is a "poster child" for species that are collected with cyanide. They are virtually impossible to collect without drugs, although a few are caught with nets in Australia. Cyanide is well known to cause latent mortality in these fish up to around 40 days post acquisition. Here is a short write-up I did on this topic:

Cyanide collection
The collection of marine aquarium fishes with sodium cyanide has been well documented and is the primary cause of death for freshly collected marine fish from certain regions. Exporters handling these fish tend to either categorically deny that this practice takes place or just sidestep the issue and say that it doesn’t really harm the fish.
In one unpublished 1983 study, 61% of a group of suspected cyanide-collected fish died within 30 days of their importation. None of the control fish housed in same the aquarium system died, and only 9.1% of the fish originating from more sustainable areas, including Hawaii and Sri Lanka, died during the same time. The sample size was 448 fish, so it was large enough to reveal a general trend.
A similar test undertaken in 2006 showed that 55% of a group of Philippine and Indonesian fish died within 30 days of importation versus 3.1% of the control fish housed in the same system. In a third study, which followed a group of marine fish for 40 days after their arrival, 55.9% of the fish from suspect cyanide collection areas died while only 6.2% of the fish acquired from more sustainable regions and quarantined in the same system (at the same time) died.
There are currently movements afoot that are helping to limit cyanide collection in the Philippines, but the problem seems to continue mostly unabated in Indonesia. There are rumors that cyanide collection is increasing in Vietnam, the Red Sea and the Cook Islands. It is not unknown for dealers to “re-label” their fish as having originated from an area that does not use cyanide. This can happen at any stage of the supply chain, so even your dealer may have been misled.

Fish has been in my tank for 5 weeks, prior to that 3 weeks in QT, prior to that at the import center.

That is past the end of when you will likely see cyanide issues.
