Question

Can you use 2 medications at once with freshwater fish i.e., internal parasite and broad spectrum (maracyn )?

Answer 1

What specific internal parasite medication are you using?  Are you using Maracyn or Maracyn 2?  Does your fish have both an internal parasite and a bacterial infection, or are you just using both because you're unsure?  Many internal parasite medications are metronidazole based, and this would be safe to use in conjunction with Maracyn (either 1 or 2).  With any other active ingredients, I would be very cautious, and probably deal with the more severe infection first.

Answer 2

Be very careful if you do, and make sure to do the proper water changes and follow directions. 2 meds is hard on them.
