Mini Porous Shrimp Cave Dome — Compact Hideout Habitat Enrichment

In a small nano or shrimp tank, even a hideout can crowd the space. Shy shrimp and small fish still need close cover that fits a compact setup.

This is Habitat enrichment: a compact porous cave dome that tucks into smaller tanks, giving bettas and shrimp a textured hideout to shelter under without taking over the layout. A snug retreat lets small tank inhabitants express their instinct to shelter and feel secure, which supports calmer behavior — and the porous surface gives shrimp a spot to graze. EnrichCove curates aquarium habitat to a science-backed standard, so even the smallest tanks can help their dwellers thrive.

• Compact porous dome cave for tight tank layouts
• Textured surface shrimp and small grazers can cling to
• Snug, low hideout for bettas and shrimp
• Sized for nano tanks and shrimp setups
• Rinse clean and reusable

A retreat your fish and shrimp use freely — sheltering on their own terms.

How do I fit it into a small tank?

Rinse it in dechlorinated water and set it low in a corner where shrimp already gather, keeping the opening clear and leaving open swimming space around it. Check it sits stable so it can't tip, and watch the tank settle over the first day. Ask your fish supplier if you keep sensitive shrimp species.
