The Sebae anemone (Heteractis malu) is a lovely addition to a reef tank, but be aware it may eat some fish out of your system. My anthias disappeared, and I never found any bodies. The anemone got larger and larger though, and I never feed it directly. Correlation? hehe The Sebae anemone prefers to bury its foot through the sandbed and attach to the bottom panel of the aquarium rather than latch onto rockwork.
This very sticky Anemone was brought home in my luggage from a trip to Long Island Aquarium. They had a tank full of these beauties, which are typically a cold water anemone that had somehow acclimated to our tropical waters. It may look like a red aiptasia, but it is quite large and VERY sticky. There's no doubt it could eat a fish if the opportunity occured. I've had it in my frag tank for the past two years, and it did split into two in that time. I feed them a few times a week with some mini-mysis while feeding the suncorals.
This image was swiped from Frag Junky (with their permission of course) to showcase the beauty of Maxi Mini carpet anemones. These are very sticky anemones that will catch fish that venture too close. Now that you know that, figure out how to set up a tank that will allow you to enjoy these gems.

A friend of mine gave me a Mini Carpet Anemone - Stichodactyla tapetum, and over time it split and made more that I could share with fellow club members. It's a very sticky creature, similar to other carpet anemones. It can catch fish that stray too closely, but for the most part mine have been well behaved. These grew to be about 1" in diameter.

This stunning creature is a Tube Anemone, taken under actinic lighting only. Like other anemones, it can close up as it traps food. This is a popular creature for nano tanks, as they stay a nice size due to their very slow growth. Their base must be buried in the sandy substrate. They are filter feeders, and do not need large meaty foods. Rather, feed it twice a week with something tiny like Cyclop-eeze or other particulate foods. It is not a suitable host for clownfish. Reef-safe-ish.
While its tentacles are straight in this particular instance, this is called a Curlycue Anemone. It looks like an enormous aiptasia, but some people like them. They are not a host for fish though. Reef-safe-ish.
This bright neon creature is a Bubble Tip Anemone, or BTA for short. BTAs are considered the best choice for hobbyists when it comes to keeping anemones, and many clownfish host in them. Do your research before making that purchase, and let your tank age for a minimum of 9 months first. This one is almost neon in color, which could indicate it is actually in a bleached condition; healthy anemones tend to have richer color and aren't as opaque.
This is a Long Tentacle Anemone - Macrodactyla doreensis - or LTA for short. WIthin minutes of adding it to my son's 29g tank, the female Maroon Clownfish quickly decided it was a great place to call home. :) As you can see, it sunk its foot down to the glass base of the tank, and tried to bury itself in the crushed coral substrate. Feeding it small meaty chunks at least once a week, supplying it with VHO lighting and providing healthy water should assure it a long life. Reef-safe.
Some comments by Michael: "The Gigantic Sea Anemone - Stichodactyla gigantea - loves warmer water (84 - 86F), and will move often if not feed. I feed mine 5 silversides a week. Intense lighting is a must (250w HQI 20,000K AB Metal Halide is what I use now), and weekly water changes. I believe clownfish are the key to keeping this anemone, because they seem to clean it daily and even bring it food. When hungry, the anemone contracts its tentacles and vibrates. Good varied flow seems to be ideal, but not directly on the anemone.
The Rose Bubble Tip Anemone is a popular choice for many hobbyists. BTAs have specific needs, and if you are considering one, please read this article first. The color is a huge plus for many reef tanks, but keep in mind that as they stretch out they will sting or burn neighboring corals to get the additional territory. The symbiosis of clownfish swimming in and out of their home is addictive. You've been warned.
