A Simple Yet Secure Little Love Shack! The Dome Breeding Cave is a 3D-printed hide designed with breeding in mind. Its smooth hemispherical shell and arched front entry create a dark, enclosed space that mimics the natural shelters fish and shrimp seek out when spawning or brooding. The low-profile dome sits flush on the substrate and won't tip — just a clean, stable retreat your tank inhabitants will claim as their own. Details: Material: PETG filament — aquarium-safe, durable, and warp-resistant Dimensions: 3.5" wide × 2" high Best for: Breeding small plecos, Apistos, Loaches, or just about any small fish or shrimp wanting a hide-out. Small enough for a 5-gallon, sturdy enough for any setup. PETG filament is a premium material chosen for long‑term aquarium use. Unlike PLA that can warp, soften, and break down, PETG is stable, strong, and temperature‑resistant. It offers better durability, water and chemical stability, and higher heat resistance — ideal for real, working tanks. Every item is printed at 100% infill, so it always sinks, feels sturdy, and has no pause lines from added weights. Many companies stop their prints mid‑way to drop in metal; we take the extra time to print each piece full of only filament for a cleaner finish and stronger structure. The result is décor that lasts longer, looks better, and performs reliably — built for aquarists who value quality over shortcuts. Designed and Printed by Puffer Pantry
