SAEs & Kuhli Loaches

Like so many here, I occasionally have trouble w/beard algae and would like to get some SAEs to keep the algae in check.  However, I have 5 kuhli loaches already established in my 29 gal heavily planted tank (along with some tetras & an Oto), and I can't imagine being able to catch the kuhli's w/o destroying the tank--they're practically impossible to catch.  So does anyone have experience with how well the two get along?  Would the SAEs scarf up all the available bottom food that I supply for the kuhli's, which can be a bit shy?  Alternatively, does anyone have a suggestion on how to catch the kuhli's to move them?
