Clownfish Ich?

[marie]

There are only 2 surefire ways to completely get rid of ich and neither is good for the liverock one is hyposalinity and the other is copper.
A hospital tank is easy to set up you just need a container that can hold water, some kind of sponge filter(keep a replacement sponge in the sump so it is already seeded with bacteria for emergencies), a heater and a small powerhead.
