Few nano questions

[spit.fire]

first question, i have a soft coral biocube setup, mainly zoanthoids and palys and for livestock i have a perc clown, a neon goby, a running crab, about 10 small hermit crabs, and 4-6 snails

would this be concidered overstocked? the clown is quite small and will be moved once it gets bigger



also what would be a good fish for a fluval edge tank? im planning on filling the tank with zoanthoids and mushrooms so it has to be reef safe
