How detrimental is useing Copper?

[Err]

I have 2 oscars, a syno cat and a bunch of little white tube shaped 1/4-1/3" long worms that have taken up residence in my tank , and I want to kill them all . Would useing copper in my tank harm the fish or the BB?

copper is awful for all living things in high amounts and you should never dose it in your tank. are the white worms attached to the fish? if not, they are most likely planaria. this in short can be reduced by feeding less and doing more frequent WC in a short period of time

Dont worry little worms will go away add salt if you must thats the safest bet but most likely wont do anything do a water change early in the morning after the lights have been out all night worms will be in gravel and they will go bye bye worked for me a few years back in my O tank.
