I think you have the SAE mistaken for the Flying Fox? I've kept a group of 5 true SAE's in my 75g for over two years now. I think they are maxed in size at about 4 1/2 - 5 inches. They do not eat my small fish or mosses. I can't comment on shrimp since i have never had any in my tank. They are only semi aggressive with each other and my Red Tail Shark bullies them all.
You did a great job with this article but in my personal experience i have never had a problem with the SAE's.
FYI, I am not confusing SAEs with Flying Fox.
