Most NA streams species do well in 50-60 degree temps which is a tad to cool for Paddle tails.
While this may be so, many streams (even cool ones) reach into the 70's in summertime. Also, achieving 50-60 degree waters in aquaria requires a chiller.
Darters do not require live foods (though it is really good to incorporate into the diet). They convert easily to frozen bloodworms and they can be used as a staple, and supplemented by other foods. if you have trouble getting them converted to frozen worms, try putting the worms in front of a powerhead or output of a filter. The movement of the worms will help give an appearance that the worms are wiggling, and the darters will strike.
