This aquarium was used for 6 months before we 'modified' it. We think the silicone adhesive came loose in a few spots and it was able to swim through the hole to get to the back. It was almost sucked into the filter. He did it twice in one day! On the same day we removed the whole block of stone and scraped the glue off the glass. Be careful using this tank, be prepared to change it out if your fish figure out how to swim backwards. I've uploaded pictures of how it looks now compared to before. We also swapped lights and filters.
