I thought that Discomed was no longer available since Aquatronics closed. It does have Levamisole in it. I'm not surprised that the expired stuff still works, but that's nice to know. It's a shame that there is so much expired stuff out there. In many cases you can judge it by the dust on the package. Levamisol also has Neomycin in it (if I remember correctly) which ages poorly. Still, I would be inclined to buy some Discomed if I found some, since they're not making it anymore. It might be nice to have on hand even if it was past the recommended use date. I haven't tried Praziquantel on Camallanus but I will if I ever find any more fish that have it. I used Praziquantel on some Corydoras metae that had a similar worm infection but it didn't seem to help. I'll be interested to hear how Susan does with her new Levamisole bolus.
