I had SAE's and got rid of them. They get big and quit eating algae. I wouldn't trust them with Cherry shrimp. I know they will eat frozen foor. I have also seen them eat live brine shrimp. They also eat delicate leaved plants like Rotala wallichi. I would get cories, khuli loaches, plecos, etc. They are great a leftover food and such. I do have to say that I have 2 flying foxes and golden algae eaters. They don't eat my wallichi. but I don't think they do much for algae either. Great algae eaters = garas, amano shrimp, ottos, bristlenose plecos....
