Whats up with my cleaner shrimp?

[Nano]

thanks brad and reefwars, I have a sliding glass lid with a plastic peice at the back thats supposed to seal up the tank, but I drilled holes all over it, cause I know fish need oxygen lol. the reason I have a lid is cause I have heard of lots of fish jumping didnt want to risk it ya know? I guess I'll have to convince my wife to let me suspend the light lol, and find brackets for hanging this light, I know they make them, but I'm sure I could get away with something different
