Tetra Parasite Guard/Jungle Parasite Clear containe Praziquantel, Dflubenzuron, Metronidazole and Acriflavin. API General Cure is only Praziquantel & Metronidazole. Both do a good job I just don't like adding meds that may not be necessary, so I suggested the GC. There are some instances where the the former would be prefered in this case I think the GC would do the job. Either way both will work so like I said if that's all you can get then by all means use it. PraziPro is always good to have on hand. Keep us posted and good luck with them.
