Pump advice re deck water feature

I have a pair of heron statues that are piped as fountains. I'd like to
incorporate them in a small water feature for my deck (standing in a
shallow basin ~3' in diameter). One of the statues is 42" tall and the
other is 36". They are piped with 7/16" O.D. tubing for (I assume) 1/2"
input tubing.

Question - can I feed both statues with the same pump, or do I need a
separate pump for each? What capacity pump can I use in each case?

Thanks
Dave
