FROSTO Aquarium Corner Hideout, Charcoal 7.5-Inch Mangrove Root Decor

FROSTO’s aquarium and terrarium corner hideout creates a sheltered underground-style retreat for small pets, with a space-saving root-inspired shape measuring 7.5 x 7.5 x 4 inches (19.1 x 19.1 x 10.2 cm).

• Corner-fitting design — creates a hideout while keeping more open habitat space available.
• 3D-printed plant-based PLA — made for use in aquatic and dry habitats.
• Open, root-like structure — lets you observe pets resting, hiding, digging or burrowing.
• Charcoal mangrove-root look — brings a natural-inspired detail to aquarium or terrarium décor.
• Made in the USA — designed, printed and packed in a small family-run workshop.

Small animals need places to retreat and explore, and a habitat corner can provide shelter without taking up the middle of the enclosure. This hideout is made for aquarium and terrarium setups where a root-inspired feature can serve as both décor and a protected space. Its open form keeps pets visible while they use the interior, and the structure can sit beneath substrate for an underground-style hiding place.

Which pets and habitats is this hideout made for?

FROSTO’s corner hideout is designed for aquatic and terrestrial habitats, including aquariums and terrariums. It suits fish such as bettas and corydoras, shrimp, geckos, snakes, snails and other small critters. In an aquarium, it offers a shaded place to rest or hide; in a terrarium, it can be partly buried to create a more natural shelter.

• For fish and shrimp: a place to rest and take cover.
• For reptiles and amphibians: a hideout that can be partially buried.
• For snails and small critters: an enclosed area for resting and exploration.

How does the corner shape help with habitat layout?

The hideout is shaped to sit against both walls at a tank corner, leaving the central area more open. Its mangrove-root-inspired contours add visual depth and are designed to blend with plants, substrate and other décor. The charcoal finish gives the piece a subdued look within the habitat, while the open interior allows pets to be seen as they shelter inside.

• Position it against two adjoining glass walls.
• Use it as a corner feature in an aquarium or terrarium.
• Compare the 7.5 x 7.5 x 4 inch dimensions with the available corner space.

What is the hideout made from?

FROSTO’s hideout is 3D printed from plant-based PLA, a lightweight material made for wet or dry environments. The PLA is described as non-toxic, BPA-free and free from harmful additives. The original design is developed and tested by the maker for pet comfort and safety, and each item is personally inspected in the family-run workshop before it is packed.

• Material: plant-based PLA.
• Production: 3D printed in the USA.
• Design: an original mangrove-root-inspired form.

How do you position and secure it?

Rinse the hideout under lukewarm water before placing it in the habitat. Set it in the corner slightly above substrate level, press it gently against both glass walls until it sits flush, then lower it to the bottom while holding it in place. Fill substrate around the base to secure the piece and blend it into the habitat.

• Rinse before first use.
• Hold the hideout in position while lowering it.
• Use substrate around the base when creating a buried shelter.

This FROSTO hideout is suited to keepers who want to add a corner shelter for small aquatic or terrestrial pets while retaining open space in the habitat. It is intended for small animals and for use in aquarium or terrarium corners; its measured footprint and height help you compare it with the space available. Its corner placement, open root-style interior and substrate-ready design make it a practical shelter feature for those setups.
