Many parasites are internal and passed on through feces to other fishes when the affected fish passes these parasites and other fishes ingest them while feeding ,foraging, along the bottom.
I applaud you for wanting to help these poor fish but sometimes our good intentions come with not so good consequences.
Treating your 125 gal tank with medications would be both labor intensive,(water changes) and expensive (buying medications).
