20G Waterbox Stocking List

[maxinf]

Hi I was wondering if my dream stock list would be sustainable. I have a 20G waterbox with 20 lbs for marco rocks (many hiding places),

2x false percula (already living in the tank)
1x peppermint shrimp (already living in the tank)
8x Blue legged hermit crabs (already living in the tank)

and I want to add

1x gamma loreto
1x fire fish

Will this be too much? I have good filtration with filter floss, matrix, chemi pure, bio balls and a icecap skimmer.

That's absolutely fine. Somethings I have to add:
You might want to increase CUC (Clean up crew). Add some snails (trochus, nerite, nasarius).
Watch for aggression from the clownfish- they are very territorial.
