First shrimp tank!

ok so after some more reading i see shrimp prefer a lower temp so i have slowly cranked my heater down to 22c. The shrimp seem alot more active now and i even had another one shed its skin. so far so good!
 
Be careful. I started with 4 rcs one year ago. I have given many away and at last count I have 287. They are fun to watch. I took a pic into my lfs and they might be interested in buying some.
 
Ok so i have finally worked it out! i have 1 female and 3 males. could this be a problem?

M/F ratio in RCS shrimp should not matter. They will breed as long as you have at least 1 of each.
