Thanks Jenn, I bet if I put it on both sides it would work.
TINNGG, I am pretty sure they didn't go over. Becasue if the drift wood placement in the tank the divider is just a bit off center, but only about 1/2 inch clearance between that and the 1" wide center brace, and the top of the divider comes about 1/2 inch over the waterline. That would be a big jump for both of them to make. Not only that, but the light rests on top of the tank, so there is very little room where they could make it without hitting equipment, HOB outflow or light fixture. These are really big fish, there is so little room for error I can't believe they both could have made the jump in the middle of the night. They're not trained dolphins- just Angelfish! If one ended up on the floor I would buy it, but I just don't see it.
