Funny. I have the same tank and was trying to figure out what I was going to do in it. Not big enough for a mantis but maybe boxer crabs or as you did, sexy shrimp. Where did you get a singe light from? I dont know much about LED but on nano tuners the other day they have a strip that is sold as a part for 49$ or something, What else if anything do I need to retro that into a 5gal marineland hex? I am guess it has the lights but dont recall seing a plug or anything. I need something really simple and easy to hook up for the hex. Maybe a couple of singles wherever you got yours from.
