Questions & Answers

Answered by real pet keeping experience.

Q How do I install it?
The suction cup lets you place it directly on the glass wall at any height, rather than sitting it on the substrate like a standard cave. Rinse before placing, then press the suction cup firmly against clean, dry glass to set it securely — reattach after water changes if needed. Mount it low near the tank floor for a ground-level shelter, or position it mid-tank where your betta already spends most of its time.
Q Will my betta actually use it?
Most do. The bulb shape creates a fully enclosed interior with a single opening — exactly the kind of space bettas prefer for resting, enclosed on all sides with one clear exit they can see and control. Being able to mount it at your betta's preferred height, up between the middle of the tank and the surface, is often what gets a betta to claim a hide instead of ignoring it.
Q Is it safe for delicate betta fins?
Yes. The smooth rounded interior and soft contours mean there are no edges or seams inside or out that could catch a fin. It's made from aquarium-safe material with smooth surfaces throughout, so your betta can move in and out freely without any snag risk.
Q Will it look natural in a planted or minimalist tank?
That's the whole idea behind this version. The organic bulb shape reads as natural in a planted or nature-style aquascape in a way angular or novelty hides don't — placed near a plant cluster or piece of driftwood, it looks like it grows out of the surrounding elements rather than being added as an afterthought. In a minimalist betta setup with clean lines and natural materials, it fits without pulling attention from the layout.
Q Is it just for bettas, or will shrimp use it too?
Both. Shrimp and nano fish move in and out of it regularly, especially when it's the only fully enclosed shelter in the tank. It's safe for bettas, shrimp, snails, and all freshwater nano species, so it works in a mixed nano tank as well as a dedicated betta setup.
Q Does it work in acrylic tanks, not just glass?
Yes — the suction cup is compatible with both glass and acrylic aquariums. Press it flat against a clean, dry section of the wall and hold for a few seconds to set, and it holds at whatever height you choose on either surface.

The suction cup lets you place it directly on the glass wall at any height rather than sitting it on the substrate like a standard cave, which opens up placement options that most hides do not give you. Mount it low near the tank floor for a ground-level shelter, or position it mid-tank where your betta is already spending most of its time. The bulb shape creates a fully enclosed interior with a single opening, which is exactly the kind of space bettas prefer for resting — enclosed on all sides with one clear exit they can see and control.

The organic bulb shape reads as natural in a planted or nature-style aquascape in a way that angular or novelty-shaped hides do not. It sits against the glass without looking like it was added as an afterthought, especially when placed near a plant cluster or piece of driftwood where it appears to grow out of the surrounding elements. It is a good choice for keepers who want to add functional shelter without introducing a themed or decorative piece that competes visually with the rest of the tank. In a minimalist betta setup with clean lines and natural materials it fits without drawing attention away from the overall layout.
