Medication

[Mahulya]

Hello.. I just added a 12" Datnoid to my BD ray and Bbxb Asian arowana tank..the Datnoid had some torn fins and white spot on both side fins..so I added methylene blue (1/3rd) dose..three days back..now I figured that it can be harmful for the ray and have also noticed rays disc getting some white small patches..How do I continue the treatment??
I have tetracycline in hand..should I put it?
I have also ordered paraguard..will be here in 2 days.. please help.. I'll arrange any medicine that is safe for the ray..

I’d carry out a large water change A.S.A.P. and get some poly filter or something similar to add to your filter.
Raised temp and salt would have cleared up the white spot.
