new shrimp tank

i've never set up a shrimp tank before
i've had shrimp before, but the addition of flagfish changed that (that or it was coincidence)

i'm suddenly curious about a tank just for shrimp.

and i know very little, ...

previously i was one of those people that put some shrimp in a tank, ogled the colors and that was that.

i'm thinking blue rili shrimp (Neocaridina Heteropoda)

small, with lots of color

i could guess a 10 gallon tank

my preferences are live foods to culture for the inhabitants, ... or in the case of algae, lots

preferences aside, ... how many shrimp could that tank hold ?

i don't want to do what i did before, ... to treat them as a novelty, so i'm asking ahead of time what to consider for their health & comfort
