A lot of them do, but I got lucky, my Mystery Wrasse's instinct is to dive down, not up. Most people have mesh tops if they have a wrasse. I do too, but I don't worry about gaps in mine due to my wrasse's nature.Are wrasses notorious for jumping out of the tank? Because that’s one thing that held me back from getting them…I had a 6-line before for over a year. No issues. But then mysteriously disappeared. I have a 125 gallon with ricks, crabs and shrimp. If it died in the rocks they would’ve made quick work of the body.
