There is a stargate in my aquarium.
Fish will jump for a lot of reasons, including escaping bullying or snapping at a tempting morsel. (My betta recently hit the lid when a gnat flew into his tank...:screwy: ) Go to Petco or Petsmart or your Mom&Pop LFS and buy a hinged glass lid. They come with a plastic strip you can cut to fit the equipment on the back. That will stop most jumping, but fish have an amazing talent for finding that one small opening....
