I'm not picking dory, but thats like saying I have had a kid for a day, and they are not that hard to take care of. Anemones live for hundreds to thousands of years in the wild. I think until you fully understand the complexity of an anemone then you should not get one feixjai.
Your clownfish will be fine with out one.
Yes they are hard to care for long term, and I don't usually consider keeping one as a success until after several years, and your anemone splitting(if you go with a breed that splits)
For long term success of an anemone, you need at a minimum VHO's or PC's, and for some MH's. YOu should also cover all the intakes to your powerheads, and overflows, and if you have a heater in your main tank then a heater gaurd as well. Also IMO if you are going to have anemones you should have a nice strong random current, so a wave maker or some decent planning of where you are going to aim your powerheads.
as far as in a 20g, here is a quote from one online store, that I would say has less than high morals when it comes to sizes for fish in aquariums
"They require an aquarium of at least 30 gallons, as they can grow up to 12" across in the aquarium."
Perhaps going with a hairy mushroom or some frog spawn would be a better solution, there is a decent chance of clowns hosting in either of those. They are easier to take care of as well.
