What Is the Zoo Med Betta Tunnel?

The Zoo Med Betta Tunnel is an aquarium accessory crafted to encourage your Betta fish to engage in natural behaviors such as exploring, hiding, swimming through, and resting. It attaches to the inside of your tank—typically just below the water’s surface—so your Betta can choose to rest either inside the tunnel or on top of it.

It’s all about behavioral enrichment—stimulating your fish’s mind and body by introducing interesting structures that reinforce healthy activity and curiosity.
