Need Anenome help.

Okay, so I'm a newbie for starters, but I've done a bit of research and what not, so I know a little bit. I've two clown fish, I forget the actual genus term, but they're nemos. Alongside, I've a goby, he's brown and has white spots and kinda just makes homes underneath rocks. I've had the tank for about a year, its a 30 Gal, and I've a heater, and a 10 w bulb that is a little bit blue, that the attendant at the store said, will promote growth and will be good for future anemones, and is all i need -- i trust her. In addition all of my levels are low, and I just introduced an anemone. to be honest with you, i don't know the name of the anemone, and I don't know a thing about it. Feel pretty silly, but here I am trying to pick anyone's brain willing to enlighten me. Literally just introduced the anemone to the tank probably 2hr ago, and when it was in the bag, it was open or whatever the term is. Now in the tank, its balled up. is this normal? My hydrometer is about 22-24 (the thing where you put water in it, and its supposed to tell you the salinity.) Now bear with me, this is a newer hobby of mine, and Im more then likely going to commit to these forums I'm just immediately concerned about it's health. , and learn all i can. Anywho, if someone could school me on what i might be doing wrong, i'd really appreciate it! Thanks all!
