Pests, Hitchhikers, and Diseases
So, a few months ago I setup a 20 gallon reef tank (see link). Aside from corals and inverts, there are currently 4 fish in the tank, introduced in the following order:
Seabe Clown
Longnose Hawkfish
Firefish Goby (pair)
Everything was going great, but about a week ago I noticed my sebae clown...
