Can u treat Blue-spot gobies with copper for ich?

[ToTaLCHaoS13]

I need to treat my entire fish population and wanted to make sure blue-spot gobies would be ok to treat. Don't want to kill him while trying to cure him!

Cupramine is the only copper that I trust and the level must be tested twice daily. I prefer hyposalinity to treat ich. Do not copper your display tank and be sure no inverts (snails, crabs,etc) are exposed to either treatment.
