Invert Stocking Compatibility?

[TwoShoesVans]

Have a 4 gallon nano that's been cycling for a month and am planning my stocking list.

Coral:
Colorful zoos and rics.

Inverts:
porcelain crab
pom pom crab
3-5 sexy shrimp
Snail or 2

No Fish

What i was wondering is will having so many inverts in the same small space lead to conflict? IE the pom pom and the porcelain?

Any suggestions for an interesting invert? that would compliment this tank, there are some restraints due to only 4watts per gallon and lower flow.

Which porcelin crab? The porcelin crab or the anemone porcelin crab. The porcelin crab is fine but the anemone porcelin crab needs a nem.
I keep a pom pom in a 90 gallon it should be fine in a 4 gallon just watch out for it stinging the coral.
The safest bet would be to add 3-4 ( maybe 2 nassarius and two astrea) snails and 2-3 sexy shrimp.

Im planning on a blue spotted porcelain crab, or a similarly colorful nem free species.

Due to the compact nature of a nano i am avoiding aggressive corals all together. Mostly soft colorful coral similar to a zoo garden with the occasional florida ric.

Edit: Miss read previous post, not too concerned about pom pom stinging coral, have one in my 30 gallon. How much damage can their feeding nems do to coral?

Are there any interesting/rare inverts that i can stock a nano besides what ive listed above?
