As long as you don't have anything for them to actually climb outside the confines of the tank, you'll be fine. Sometimes, shrimp climb out because they don't like the water params too so hopefully that's not your issue here. Is she the only one you seen do this so far?
Ya she's the only one who did it. Think there was some tasty bits around it. She did a couple laps and went back in the water like nothing happened. It seems like she would get herself wet then go up there and eat till she started to dry out and went back to the water. Funny stuff, everyone seems happy so I don't think it's water quality problems.
