help save the clownfish

Look up brook or brooklynella. It is known as clownfish disease and is common in new fish. Unfortunately it is almost universally fatal if not treated. The usual treatment is formalin and/or copper.

Do a search and if you are fairly sure that is what it is start treatment as soon as possible.

The treatments are quite toxic so just treating because it "might" be brook is not recommended. Pictures would help.
