Corals Doing Great...just Having Trouble With Id...

[connorsbala]

Hey,
Just to let you know my tanks been up and running for about 3 months and i put my first pieces of coral in 3 weeks ago
I feed the fish everyday, a good variety ( hikari marine sinking pellets, flake stuff with freeze dried brine shrimp and krill, frozen krill, live brine shrimp, frozen plankton (if they steal some from corals) and ive been feeding the corals some red sea coral grow liquid every other day.

Here's a pic of the tank before with just the LR in during the cycling process

Here it is now with a couple of corals in

Now for the questions,
I went tot he LFS and the marien guy was away so i had some guy who didnt know which was which so he charged all the corals at 24.95 each

Here they are, please help me with identification and feeding

Christmas tree (this was 11.95 btw lol)

Green xenia or something, heard it was easya and hardy

Not sure, some type of finger

Dunno, colt maybe?

Please help as i want to find out their names and do some further research
In the half term my dad's taking me to wildwoods where they have loadsa nice corals and ill be getting a hammer/anchor, frogspawn and soemthig else that take my fancy lol

Thanks

Green star polyps, or maybe green clove polyps. Very similar corals. Yes, a finger leather, and a colt coral too
