will this be overstocked?

[cathyg_99]

90 gallon tank with the over flow is really more like 82-85 gallon would this be overstocked?

currently i have

1 yellow tang
2 blue chromis
1 firefish
2 picasso clowns
1 mandarin goby
1 pepermint shrimp
8 blue leg hermits
4 turbo snails
4(i think i rarely see them) sand sifting snails
1 sand sifting starfish
1 emerald crab
1 porcelain crab

i would like to add:

1 cleaner shrimp
1 wrasse (thinking of a fairy but might do a six line)
1 tuxedo urchin
1 firefish

maybe another show piece fish hippo tang, or something else (any suggestions)
