Brody, no just used once on an art project for my daughter, used to glue twigs to a fish bowl, the stuff was strong! But yeah I didn’t think about a redo or removal...silicone would be semi-permanent and a better solution. I used to do glass work...1)use painters tape to hold the perch in place 2)silicone to tank 3)let dry, 4)remove painters tape, 5) MOST IMPORTANTLY make sure painters tape and silicone never touch. We used that trick all the time...
