Tunnel Essentials

Everything your Betta's new hideout can do

A fin-safe hideout for curious Bettas

This S-shaped tunnel gives your Betta somewhere to swim through, hide in, rest near the surface, or build a bubble nest around - all without a single sharp edge to snag a fin on.

Built to last, not to peel

Made from durable, non-toxic ABS with color embedded right into the material, not painted on. No flaking, no chipping, nothing leaching into your water.

Aquarium-safe ABS plastic

Color is embedded throughout the material during production, so there's no surface paint to chip, peel, or leach into your tank.

Sized for standard Bettas

Approximately 16cm long (6.3″), 10cm tall (4″), with 5cm (2″) openings - ideal for most Betta tanks, even smaller setups. Best suited to standard Bettas and smaller fish; may be snug for a fully grown King Betta.

Comes with suction cups

Attach it securely to the glass, or set it free on the substrate - it's built to work either way.

Try it a few ways

  • Upright against the glass, just below the waterline, for a resting spot with some air exposed at the top
  • Flat across the substrate for an easy swim-through
  • Paired with a second tunnel for a maze
  • Tucked in with live plants for a natural-looking hideaway

Easy to keep clean

Rinse it in tank water and scrub gently with a soft brush (a toothbrush works great) if algae builds up. Skip the soap and chemicals - they leave residue your fish don't need.

Why Bettas Love It

Why Bettas Love Our Tunnel

It's not just a decoration. It's a hideout, a playground, and a resting spot all in one.
Helps Reduce Betta Stress

Helps Reduce Betta Stress

In the wild, Bettas duck into roots, overhangs, and other spaces to feel safe. This tunnel mimics that natural shelter, giving them the perfect spot to chill, explore, and sneak away when they need a break!

Helps Encourage Activity

Helps Encourage Activity

Bettas are born explorers, and a dull tank just won't cut it! This tunnel adds a playful twist to their setup, giving them a spot to zoom through, peek out from, and weave around, keeping them active and living their best Betta life!

Helps Support Rest & Happy Bettas!

Helps Support Rest & Happy Bettas!

Bettas love to lounge, and a cozy hideout near the surface lets them rest and breathe with ease. This is extra important for long-finned Bettas, who use more energy just to stay afloat - carrying all that fin flair is harder than it looks!

FISHKEEPER QUESTIONS

Everything Betta owners ask first

  • Yes! The Perky Fins Tunnel is designed with smooth edges and perfectly sized openings to help your Betta swim, play, and explore comfortably—without getting stuck or snagging their delicate fins. It’s made from aquarium-friendly materials and the color is embedded during production, so you don't risk peeling paint contaminating your tank water!

    But don’t just take our word for it. Our Bettas Apollo, Hades, Poseidon, Ares, Helios and Zeus give it five fins!

  • Not at all! The vibrant colors are embedded into the material during production, so there’s no surface paint to chip or peel. That means long-lasting color without worrying about flakes in the water. It’s built to stay bright and fish-friendly for the long haul!

  • The tunnel is approximately 16cm long (6.3″) 10cm tall (4″) and has 5cm (2″) openings, making it ideal for most Betta tanks, even smaller setups. Its compact yet spacious design fits seamlessly into a variety of tank layouts.

  • The tunnel is incredibly versatile! It comes with suction cups so you can fix it to your tank securely.

    Our Bettas enjoy it when it’s upright against the side of the tank. If you place it towards the top of the water line, leaving some air exposed in the top opening, it makes a great Betta resting spot!

    But you can also lay it across the substrate for a cozy swim-through, double it up for an exciting maze, or pair it with plants for a natural hideaway.

    Feel free to experiment and find what your Betta enjoys most!

  • Our tunnel is crafted from high-quality ABS plastic with embedded color throughout, so no surface paint. It’s made with materials commonly used in aquarium-safe products, so you can feel good about adding it to your tank.

  • Cleaning is simple! Just remove the tunnel from the tank and rinse it in your tank water. If needed, use a soft brush to gently scrub off any algae or debris (we use a toothbrush!). Don’t use ANY chemicals or soaps, as they can leave residues harmful to your fish.

  • Absolutely! While it’s designed with Betta fish in mind, the tunnel can also be enjoyed by other small fish, shrimp, or aquatic creatures that like to explore and hide.

    Our shrimps love it!

  • The Perky Fins Tunnel is ideal for standard Bettas and smaller fish, but it might be too snug for a fully grown King Betta. We recommend checking the dimensions and considering your fish’s size before purchasing.
