So this is my first open top tank I've had and I'm worried about the shrimp climbing or jumping out of the tank. Does this happen often, any of you guys have jumpers in your tanks and how do you get around it? I like the open top look so would prefer not to stick a lid on it. I could get a piece of mesh cut to size for it but was wondering if its worth it or not. If its not a common issue then I won't bother getting mesh.
