So just bought these from Walmart. Thought these were pretty interesting. Basically these are alarms u place on ur window/door. When they separate they go off. Thought about maybe placing one of these on the lid n the other counterpart on the actual tank, kind of like an arowana jumping out tank alarm system. Obviously just better idea to weigh down tank and prevent the jumping, but just thought it was an interesting idea. Hows all the aro keepers doing?
