Whats the best medicine to treat it assuming it's an internal parasite? It has to be safe for young fish and crawdads.
lol little to much faith in prazi...prazi is NOT effective on hexamita. Metro is the preferred treatment.I've always use prazipro and ill stick by it no matter what. Your fish are probably dealing with some sort of hex. Prazipro will effectively kill ALL parasites while leaving the beneficial bacteria unharmed. First when you put it in the fish will sink and act like their taking a crap, they'll be fine in the next 10 mins so no need to feel alarmed. You need to keep it in the tank for a recommended two weeks I believe? Can't really remember what the bottle states but I'm pretty sure its 2 weeks.. When you water change dose the new water with prazipro and this will kill EVERYTHING you don't want in your tank including in filter media, gravel, hoses, etc.
With metro, all it does it promote fish recovery and aid in hole in head diseases.lol little to much faith in prazi...prazi is NOT effective on hexamita. Metro is the preferred treatment.
