Clear Acrylic Betta Tunnel — See-Through Habitat Enrichment for Bettas

A nervous betta needs cover, but a solid cave can hide it from view all day. You want your betta to feel secure and still get to watch it.

This is Habitat enrichment: a small clear acrylic tube tunnel that gives your betta a sheltered passage to rest and explore while staying visible through the see-through walls. A tunnel satisfies a betta's instinct to shelter and patrol enclosed spaces, supporting calmer, more confident behavior — and the clear acrylic lets your fish hide without disappearing. EnrichCove curates aquarium habitat to a science-backed standard, so your betta can thrive with cover you can still see it enjoy.

• Small clear acrylic tube tunnel
• See-through walls keep your betta in view
• Sheltered passage to rest and explore
• Sized for betta tanks and small aquariums
• Rinse clean and reusable

A retreat your betta uses freely — sheltering and exploring on its own terms.

How do I set up the acrylic tunnel?

Rinse it in dechlorinated water and place it where your betta already spends time, with both ends open so it can pass through easily. Check the tube is wide enough that your betta won't get wedged, and watch the first day as it explores. Ask your fish supplier or an aquatic vet if your betta seems stressed by new decor.
