Just purchased a brown sailfiin tang/ Scopas tang got hin home from the lfs and after acclimation, fed (alot they just dont eat well in the shop) so now its gotta poop, a? K all good with that BUT this is a wad of string- looked it up best i could and found it to possibly be "threadsworms" fish looks very healthy, ate fabulously. So i'm either catching this earlie(fingers crossed) or miss diagnosing. The treatment says food soaked in Parachlorometaxyenol. K all good with that BUT its toxic to fish(????)... any ideas? ne 1 had to deal with this?
