I'd like to look into adding shrimp to my aquarium in the future. Not a for sure thing yet, just thinking this out now. I'll read into the water parameters and whatnot, but the main question i've got is; Do I need a lit or top to the tank with them? I've seen shrimp jumping a lot in the water out here, just thought about this the other day. I kind of like my tank without the glass top. It's nice.
