my plan is when my silver outgrows my 150 to move it to my 1200 gal indoor pond (8'x8'x2' plywood with 2"x4" stud framed walls and a pond liner) and hang thin sheets of plexiglass from the ceiling to the 3 open sides of the pond (4th side of the pond is up against a wall) too keep the aro from being able to jump out but still able to jump up. anyone ever see anything like this before? anyone see a downside with this idea?
