Bicolor blenny looking rough in QT

[154162]

Hi, I got this bicolor blenny on oct 7th (9 days ago) he’s been in QT, no treatment just observation.
when I first got him he was kind of brown all over (showing his stress Colors) he had just gotten in the Lfs that same day) which seems to be normal, he has been colouring up the last few days, but then I notice now he’s getting paler and more flesh pink kinda colour... his side fin seems to be damaged as well as his dorsal fin, and maybe some damage on his side too? Is this a disease or just physical damage? I’m in Canada so meds are really hard to come buy, i do however still have copper on hand but don’t think that’s going to help...
Any help would be appreciated
Here he is now:
(Please don’t judge the bottom glass he’s getting his water change tonight :/)

Here is the blenny when he was looking brown a few days ago

Sorry, that looks like it could have been a protozoan infection known as Brooklynella. Given the time frame, you wouldn’t have been able to treat it. I think you might want to strip and restart the QT. Also, see if there is some way you can get some medications in, copper in particular.

Thanks!
Yeah tank is getting sterilized and dried out tomorrow.
Copper power; that’s the one I did actually manage to get, but that’s it!

Put some pvc pieces or some type of hiding spots that u can easily sterilize next time. Not having places to hide can stress blennies out

Blennies get stressed very quickly.
