fish for a 16-18 gallon?

[mr.p]

just set up a 16-18 gallon tank not sure probaly 16. I was wondering later on if any of these fish would work? and also how hard are they to keep? =) thank you!

:happyfish
bi-color angel ( I know they get around 4 inches but is it usually quick? and would they go crazy in a smaller tank if bought small around 2 inches?
niger trigger( same thing above I've seen them about 2 inches or a little less and do they usually get big fast?
humu humu trigger ( same as above)
pygmy angelfish
any of these i'd like to know about thank you!
if any of those don't work would this be okay?
2 firefish
1 royal gramma
1 tomato clown
mayb 1 pygmy
5 or 6 hermit crabs
maybe a cleaner shrimp or some small one.
along with live rock 15-20 pounds
20 lbs of live sand.
right now i have 20 lbs of live sand how can I tell if it's still alive? also 5-6 lbs of live rock.

im sorry but the all the triggers and angels will out grow that tank so fast hummus and nigers need a 75 gal. min. i would do 2 firefish and a shrimp

for a 16 gallon... You could probably only keep an inch or 2 or 3... So probably 2 small fish.
Maybe a couple of false clowns or a couple of damsels or whatever.
Forget about the trigger and angels!
Out of your list, id get 2 firefish, they're very nice!

or go with a pair of either percula or false perc. clowns. tomatos need a little more room to swim around....i wouldnt try any pygmy angel either. not saying it isnt possible, just wouldnt recommend(sp) it. good luck with the tank!

Thanks guys I appreciate it! That's why I was curious to know how big the triggers get, I have a bigger tank I would be able to move them too but since they get big fast then yeah not a good idea.
