Fish in 045 ppm Copper for 5 weeks but still scratching?

[Hokies83]

Have 2 clowns 6 line and Blenny.

All have been in from 0.4 to 0.45 ppm copper for 5 weeks but there still scratching there sides every now and then on the plastic pipe in the Hos tank?

Asking because this is there last week in copper Then a week off then Pazi pro for 2 weeks.

Prolly flukes. Fw dip them or do a prazi dip. Or just start your prazi run now depending on which copper product you used you can run them together. I use copper safe and prazi together. But copper at 2.5 or less unless I see ich come out. Also at that high of copper dose it may be irritating their gills.

I sure hope you mean .4 if cupramine, if using a chealated 3ppm is the highest you can dose. If your test is actually 4ppm then the copper is most likely irritating them, otherwise as stated above, flukes will cause flashing also.

Yeah Sorry it is between 0.4ppm and 0.45 ppm it is cupramine.

Pazi Treatment starts in about a week.

Sometimes fish can still display symptoms even after what was ailing them is gone. For example, damage done by Ich trophonts feeding on a fish's skin/gills will oftentimes still iriate the fish even after the trophonts are gone. So, the fish continues scratching to relieve it's symptoms. This usually subsides in time IF the trophonts do not return.

But doing two rounds of Prazi is still a good idea while you're waiting for the fish to stop scratching.
