More Bn Pleco Problems

Okay, what is everyone's secret?
My new male BN Pleco is now breathing too fast, like my other one (RIP buddy). I'm thinking it's the same culprit.
(look on 2nd page)

I have access to Quick Cure (Formalin and malachine green), which I know is dangerous to scaleless fish.
I have access to APPLUS+ Anti-Fluke and Jungle Parasite Guard, which are organophosphate, also dangerous to scaleless fish, or so I've read.
And I have access to Jungle Parasite Clear Tank Buddies.
Which medication would be best under these circumstances? There will be Praziquantel coming shortly, but that could take up to a week. And if the BN Pleco does have the gill flukes, he won't last a week.
This could be the 3rd one dead in only a few months.
This is almost too much.

Ph:6.5
Ammonia:0
Nitrites:0
Nitrates:5-10
GH:1
KH:1
Tank size: 33 Gallons (Medium Planted)
Fish as of this moment 5 colombia tetras, 2 zebra danios, 1 longfin blue danio, BN Pleco ( Cories are not doing well, but that is under control in a seperate tank )
40-50% water changes weekly.
AC 70 filter.
Temp: 25C

Anti fluke med but go in with half dose, and really increase aeration, don't forget to remove black carbon, good luck, gill flukes soon can kill a fish, look out for bacterial infections as well.

Thanks. Removed carbon. Used the Jungle medication, as it has Praziquantel and is less dangerous for my pleco, or so I have read.
It also did well the last time I had external parasites.
Thanks for the response.
