and I got a anti anchorworm medicine, but Its an Organo Phosphate compound. Its Dimethyl- ,2,2,2- trichloro-1-hydroxy-ethylphosphonate Is it safe to use in a Snakehead? Please help

that is trichlorfon, surprised you found any as they stopped making it. I use it (api lifebearer antifluke) on my discus for flukes and it is safe, there are otos and ancistrus plecos in the tank too.
