I have been a member of CompuServe's Fishnet forum for over 10 years, and America On-line's Pets Forum for 2 years. In my experience, of the two, CompuServe is the better choice for reef-related advice, quality of information available, quality of discussions and the level of expertise of its members. America On-line is easier to use for the novice, and has many excellent files on a variety of topics available for downloading. One thing that really bothers me about the AOL Pets Forum is that their chat rooms are shared by everything from cats to parrots. Nights are designated for certain topics but people often intrude on fish or reef discussions, this does not happen on Fishnet since it has its own chat rooms devoted only to fishy topics.
Flatworms come in many shapes and sizes.
They can be brown, green or red, often with a white strip down the middle of the back. These animals feed on bacteria and coral slime and are thought to be relatively harmless. The problem comes when you get a population explosion in the tank and they begin to cover every available surface, including your corals. They become a real eyesore and can also severely cut back on the amount of light the corals receive. Fish are the most effective biological controls for flatworms.
