New to hobby need some help

[TroyPais]

Hi folks,
I'm new to the hobby and I was wondering if I could get some help, first I'd like to know if the placements of my corals are fine or if I should move any of them. Secondly I'd like to know what kinda corals are the ones that are in the middle of the tank sitting in the sand.
The tank has been up for 7 months now and my LFS says my water parameters are perfect.

The picture I have uploaded will show from left to right. Pulse xenia. Green star polyp. Neon blastmusso. 2 unidentified corals. Short gone. A meaty coral? And a orange orange mushroom ricordia. I also have the hammer and frogspawn and 3 zoa drags.

Just need some help figuring out where to put the corals for optimal growth and looks.

I have a 20g innovative marine tank, Sicce Voyager Nano Powerhead (530 GPH), Hipargero Aquarium LED Lights 30W Saltwater Lighting

It would help if I put the picture up as well

No pix. You need a post count to get the pix sharing permission enabled.

You can use a photosharing site such as imgur, photobucket, etc and share the link within your post.

That looks pretty good to me. I would be careful with the green star polyps, because they tend to try to blanket the planet. Having it on an island the way you have it is a good start, but keep in mind that in time that rock may get 100% covered.

Always start on the bottom and move up if required....let them tell you by extending.
You say 30w light on a 20g.....that's not enough for corals which require light which is almost all...you should be in the 150w range....for best results

Cool maybe I can return this light and try and get another one

Thanks so much for the advice

I'm still trying to figure out what the corals in the middle are and the one next to the mushroom ric. My LFS gave me a name but I forgot it lol
