From Rose Bubble Tip Anemones, Rock Flower Anemones, Condy Anemones & Tube Anemones, AquariumDepot.com has an excellent selection of anemones.
Care of anemones is easy as they simply require medium to strong light and typically prefer stronger flow. A weekly meal of a small piece of fish such as a defrosted quick frozen silverside (piece approx 1/2 inch depending upon oral opening size) will allow the anemone to grow and even reproduce often in the home aquarium. If the anemone has a clownfish host, the clown can be handed the piece of fish and will eagerly take it to the anemone and feed it. This symbiotic relationship is an incredible experience to observe.
