I just did some reading to refresh my memory of things. There are two similar
parasitical diseases, one of which is oodinium and the other cryptocaryon.
Either may be called "ick" by some people, but crypto is usually what is called
by that name. Oodinium is usually called "velvet."
Oodinium shows up as a hazy coating on the fish -- the parasites are pinpoint
size and hard to see. The usual symptom is that the fish dashes its gill covers
against decorations, trying to scratch the itch.
Crypto is also called "white spot" -- the parasites are pinhead size.
Both parasites respond to copper treatment, but crypto also responds to
treatment with sodium sulphathiazole, which will not hurt invertebrates.
Oodinium will not respond to this treatment, but, if all you have is white spot
disease, you might try this.
Caveat -- My book is a 30 year old copy of "The Marine Aquarium in Theory and
Practice." The medicine may no longer be available.
