Alien Aquarium Hide - Betta & Shrimp Cave - Sci-Fi Fish Tank Decor

Give your aquarium a futuristic focal point with this alien house hide, designed to stand out while giving your fish and/or shrimp a comfortable place to retreat. The rounded, enclosed shape creates a natural sense of shelter that bettas, shrimp, corydoras, loaches and other bottom dwellers are drawn to. The open doorway allows easy access, while the interior provides a shaded space where fish can rest and feel secure. A customizable sci-fi panel above the entrance lets you personalize the hide with a name or short phrase. It’s a simple way to make your tank feel more personal, whether you’re naming your fish, creating a theme, or giving it as a gift. Each piece features a clean gray body with subtle colored accents for a modern look that fits both natural planted tanks and more stylized setups. Available accent colors: blue, green, and pink Dimensions: 3.25" high, 3.15" wide, 3.5" deep - Need a larger size? Select hides can be made in custom dimensions. Send us a message with the size you need, and we’ll let you know what’s possible. Made from aquarium-safe PLA plastic and 3D printed for consistent quality. During initial placement, a small air bubble may be trapped inside the piece, causing it to tilt or float unevenly. To ensure proper positioning, fully submerge the item and slowly rotate it in all directions under water until all air is released. If the item appears tilted or uneven after placing it in your tank, this is almost always due to trapped air and can be resolved using the steps above. Each item is made to order, meaning it’s specially created just for you once your purchase is placed. Because of this, we do not accept returns or exchanges. However, if your item arrives damaged or you feel it does not match the description, please contact us within 30 days of delivery and we’ll be happy to help make it right. Behavior Disclaimer: Bettas, shrimp, and other aquatic pets each have unique personalities and habits. Some may immediately use this hide, while others may take time—or may simply prefer different areas of the tank. This is normal animal behavior and is outside our control. Returns are not accepted due to a pet choosing not to use the item. Every image in this listing shows the actual 3D-printed product, not a mockup or digitally altered product image. We test our designs in real aquarium setups with aquarium animals so we can better evaluate fit, function, and everyday aquarium use.
