I added this to my 20-gallon tank for my mousefish. It’s easy to place and the fish immediately started using it. The structure stays firmly on the bottom and doesn’t float. No issues with water flow or fish getting stuck.

Works well as a simple hiding spot. The design is transparent, so water moves freely. I placed it against the back wall and my fish use it regularly. A good option for beginners.

Great for small tanks with limited space. The material feels solid and doesn’t break or disintegrate even after several weeks. My fish feel safer with this hiding spot.
