I need to temporarily hold pacus(5in) in a 180 acrylic tank for a year or less. I was told that would be just enough time before they are too large. Now I was considering using cork bark covered with thick willow moss(looks like moss carpet) on the entire back and sides.Tank could only be viewed from front. I am wondering if this would help against the occassional thump into the tank(from pacu) and help keep the tank together long enough.
