29g Coralife biocube setup and stocking ideas?

Hi all,

I've had my tank running for a month now and wanted to run some thoughts on stocking it. I'm hoping for some more of the great advice I have already received on the initial setup!



tank:

29g Coralife biocube (2014) with the stock lighting (white CF tubes, blue antics, and blue moonlight).

@ 20 lbs cured live rock

5 lbs live rock

30lbs live sand

1 hydor koralia 425 powerhead

stock filtration (bioballs and carbon) + Purigen on top



What we currently have in the tank:

critters/CUC:

1 fire shrimp

1 hermit crab

7 snails



fish:

1 clownfish



The tank is running great; water looks good and am thinking about what to do next. Our ultimate goal is to have a reef of mushrooms, zoa, and some LPS corals, along with a few fish and inverts, but I'm not sure how to balance the bioload of fish/inverts/corals... (For my freshwater tank, I always went with the 1" of fish per gallon - is this the same with a mix of inverts/fish?). We have two small boys (2 & 5) and we really like using the tank as a teaching tool. The more movement, the better.



Here's what I would like to add critter/fish-wise:


1 additional clownfish (for 2 total)

1-2 banggai cardinalfish

1 goby

1 firefish or Tanaka's pygmy wrasse

1 pistol shrimp

1-2 additional hermit crabs (for 2-3 total)

1 brittle star (??)

1 fan worm/feather duster



** thinking of getting the copepods mixture to feed/breed in the tank - do people like this/recommend?



(I also really like dartfish, anthias, and chromis, but am guessing that five or six, 1-2" fish are probably about the limit for the tank.)



Any feedback on stocking, filtration, lighting? We have looked into replacing the lighting with the Steve's LED Light System, but wanted to see if that was actually necessary for the types of corals we want to grow. Our current filtration seems to be working great, but am open to suggestions too!
