The tunnel looks beautiful in my fish tank. My betta fish enjoys swimming through it. The silicone covers stay sealed well and the water stays in even when the tank is tilted. The planting tray is perfect for adding live plants.

It fits nicely in my 10-gallon tank. The water retention is excellent and the fish seem more active when they can swim through the tunnel. The mirror attachment works well for adding visual interest.
