The anemone and clownfish combo lure a lot of people into this hobby who then get frustrated and quit due to the difficulty of keeping anemone's.
Be wary, with a young tank with that little water volume keeping an anemone will be a large task. Besides, almost any hosting anemone will outgrow your tank in short order as they all can get huge. Some dedicate entire tanks larger that 55 gallons to anemones.
The are many controversies in regards to keeping an anemone. Some will insist that intense lights are necessary, others will tell you that feeding an anemone allows you to keep one under low light. At one time, it was believed that you couldn't keep an anemone alive for an extended period of time. Certain anemones fair better in the home aquarium, ie the bubble tip and carpets. Carpet anemones can eat your fish, even large ones. Haddoni carpets require more light and buble tips less. Sebae anemones are more difficult to keep. The easiest anemones to keep are the atlantic Condy's but they are not host anemones.
With that said, allow me to talk about my experience with keeping them. I originally had a 55 gallon reef with 4 40 watt NO lamps and tried a
green carpet anemone. Despite feeding and a host clown, he shriveled up and died over a period of months. When I upgraded to a 100 gallon tank about a year later I tried again. This time I had 400 watt MH lamps and a dsb. I had that anemone for over a year (a fraction of their lifetime) and it grew exponentially. Earlier this month, I traded that anemone in for a
blue carpet anemone. It gets fed occassionally when it gets fish food that floats to it, and about every other week I feed my carpet a silverside. I have no clowns in the tank, so no host at present.
That is just about all I know about anemones, but the only anemones I'd recommend for a 10 gallon tank are aptasia
