The Green Mushroom Corals are also referred to as Mushroom Anemones and Disc Anemones. This variety of mushroom coral is various shades of green. They are a wonderful invertebrate for bottom placement in a reef aquarium. Over time, they will reproduce, forming a carpet covering the rockwork and sand.
They are hardy and easy to maintain. In general, they need a medium light level, and should be placed lower in the tank if the light intensity is high. These mushrooms require a low to moderate indirect water flow. Too much water movement will inhibit these mushrooms to fully expand. They are semi-aggressive and require adequate space between themselves and other corals and sessile invertebrates.
The Green Mushroom receives most of its nutritional requirements through symbiotic algae zooxanthellae hosted within its body which provide the majority of its nutritional requirements through photosynthesis. It also feeds on other nutrients and particulate matter and benefits from additional food in the form of micro-plankton or brine shrimp fed to each polyp of the colony.

The Rhodactis Hairy Mushroom is a member of the order Corallimorpharia and occurs in many colors including brown and tan, and the more colorful green. Like the name suggests, the surface of these mushrooms are covered with many hair-like tentacles, giving it a hairy appearance.
It is very easy to maintain in the reef aquarium, and a good choice for the beginner hobbyist. It is somewhat aggressive, however, and can harm sessile invertebrates and overgrow other inhabitants of the reef. It often grows in shallow water, so it prefers a medium to high light level combined with a medium water movement within the aquarium.
It reproduces by fission or laceration, and will do so in the home aquarium provided that water conditions are adequate, sometimes causing over-population. A small portion of the base or mouth will separate from the parent polyp and grow into a full sized mushroom within a few months.
The symbiotic algae zooxanthellae hosted within its body provide some of its nutritional requirements, but it also eats plankton and some larger organisms.
SEEEEE...I did read stuff....I don't see where it says it eats fishies..
I guess I am just not looking in the right places for information
