would organophosphates hurt his channas?Fish lice (argulus) are tough buggers, If they have had a chance to breed it is best to treat the tank. There are at least 150 species and most are salt resistant and can survive any temp that the fish can. Most meds for them are potent mixes of copper sulphate and organophosphates like trichorfon (Dilox), General Cure is one brand.
