Other people have probably told you this already, but I would strongly advise against anemonies.
In the wild, clownfish only live in a handful of different kinds of anemonies (each species usually have 1 or 2 that they'll live in) and those species are the more difficult ones to keep in the aquaria. They need pristine water, really good lighting, etc. They also live thousands of years in the wild, so there are ethical issues to keeping something like that in captivity where the best you can hope for is like 5-10 years.
Sometimes in the aquaria, certain species will go in species of anemonies other than their natural host, but whether or not it happens is luck of the draw.
The good news is that they do just fine in the aquaria without anemonies.
I'd recommend a hardy species like one in the Tomato complex (A. frenatus, A. melanopus) etc. I had a melanopus for a few years and really liked him (I ended up taking down the tank and giving him away, though).
If, in a few years, you've refined your skills, then you might be able to try a hardy, atlantic anemonie such as the condylactus.
