Ok, lets start at the beginning. Please excuse the fatherly tone for a minute, but... you shouldn't put anything in to your tank that you haven't put some thought into ahead of time, that includes knowing the species of what you're buying as well as its needs and how it'll interact with everything else you have in your tank. Buying off impulse, which it appears you did since you don't know the species of either, is not only bad for your wallet but bad for the livestock.

Ok, end fatherly tone.

That said, it looks like you have an ocellaris clownfish or a percula. Without being able to see the dorsal spines clear enough to count them, I'm not sure.

Now to switch back to Debby Downer mode.
The anemone... well, don't worry about what kind it is because, to be blunt, you need to take it back to the LFS. I've had quite a few anemones, and as you will find the general consensus, they do not fair well in new tanks, there's exceptions to the rule as always, but it's really not likely. After a year or two of maturing, your odds of survival sky rocket, before then, they're likely going to die and pollute your tank. Now understand that I have a bubbletip in my 3 month old Biocube, but I've also had somewhere between 7-10 of them in the last 5 years, all of which lived to 2 or more years before being sold, and I've only had one die on me. I knew the risks and decided I wanted to challenge myself and the very notion I'm telling you right now, but the bottom line is, it's probably going to die, you should take it back and try to recoup some of your cost.

That said, you don't need an anemone for your clownfish. Is watching them be hosted by one cool? Oh **** yes. But the even cooler part is that they can be hosted by just about anything. Bubble coral, hammer coral, button polyps, heck people have had them 'hosted' by their powerhead before. Given the age of your tank, a coral would be much more suitable as it's odds of survival, if you research the species before hand and make sure it's something you can care for in a new tank, are much higher.

If down the road you get an anemone when your tank is better suited for one, you will also find that the clownfish may decide to go sit in it the very day you put it in, or it may take a week, or a month, or a year, or it may never happen. Even if you match the favorite anemone to that species clownfish, there's no guarantee that it'll be hosted. By providing multiple coral choices though you increase your odds it'll be hosted by *something*.

Sorry Just telling you the honest truth about the situation.
