This is a Condylactis Anemone, a great biginner anomone, as the requirements for this type of anomone are not as "demanding" as some others. As with any anomone, it is a good idea to ensure that this animal is only introduced to an established aquarium (I say a year.. but there are a lot of varied opinions on what "established" really means)
This is a photosynthetic animal but it also needs to eat frozen or fresh fish food preparations. At a minimum, I would recommend at least power compacts with 50/50 bulbs (full spectrum/actinic) along with supplemental feedings every other day, or twice a week. Fresh seafood from the local market such as shrimp and clams work well. Cut the fresh, uncooked seafood into very small pieces and use tank tongs or a turkey baster to deliver the food to the anemone's mouth.
You should be warned that they can move around the tank, albeit slowly. This means that you will need to use foam filters over any power head intakes. Many hobbyists have lost anemones because of an unprotected power filter intake! You will probably not want to keep them in a reef tank with corals because they have a sting that can harm corals, fish and other anemones.
The anemone is not a "natural" host for the clown fishes. However, some people have reported success with keeping clown fishes with their Condylactis Anemone, whereas others have reported the demise of either the clownfish or the anemone after the introduction.
This can be an interesting anemone to keep and it can be a good one to start with, provided that you can meet some of this animal's demands detailed above.
Some folks think that the key to success for this animal is performing frequent partial water changes (10 - 20% every 2 weeks), supplementing with iodine, having the right light intensity over the tank (at minimum - Power compacts in short tanks and HO, VHO or Metal Halides in tanks deeper than the standard 24 inches) and supplemental feedings with a variety of fresh marine foods.
Hope this helps.
