Copper with Java Ferns and Clown Loaches

I treated my ich infested tank, containing three very young, badly infested 
clown loaches with a single dose of Coppersafe at the full recommended 
concentration (from the bottle).

The clown loaches were apparently undamaged by the copper, and the ich was 
eradicated.  A very robust Java Fern was completely wiped out, along with a 
bunch of other plants that hadn't been doing so well.

Next time, I'll quarantine....
