Also what about bamboo shrimp (my LFS has them and they look cool)
as far as i can tell they are. correct me if i am wrong SAE have a little yellow on the fins and flying foxes do not?
I wouldn't go with bamboo shrimp (just my opinion). You would end up having to feed them supplementally as they are filter feeders.
I am not sure what 90's and 45's means (I am kind of dumb)
