[brettmc]

This is just my "first draft" of inhabitants for my 30g cube (20x18x21) with a 175w MH, and 2x24 CF's, with of course LR (not sure how much right now) and probably 3-4" LS. A skimmer, and 1 or 2 powerheads will be included too. Here my list of things wanted right now, let me hear your opinions good or bad any help would be greatly appreciated. Thanks.

-Gorgonian - carribean encrusting
-Waving Hand Coral
-Xenia
-Zoanthids
-mushroom polyp
-Ricordea
-Montipora
-Pocillopora
-Porite
-Brush Coral
-Finger Coral
-Feather Duster
-Cleaner Shrimp

-Some hermit crabs
-Chiton
-Tridacna Clam
-Bubble shell slug
-Blue linckia starfish
-Short spined brittle starfish
-Long spined urchin
-Cucumber
-Clown Fish
-Goby

Sorry about that being such a long list. Also keep in mind I'm a beginner, but I've been doing my research for the past couple of months and I'm still going to be for the next month or so.

I'm gonna need to see the stats on your tank before i can really get into it.

Whoops, sorry I forgot to mention up there, that I have none of this equipment yet, except for the light (which is in the mail). I'm waiting until I move next month, just basically checking compatability and whether or not I should wait until i'm more experienced before getting some of these animals. Thanks for your help.
