💀 YOUR FISH TANK JUST GOT A MAJOR GLOW-UP!
Let's be real — a plain gravel bottom is boring. Drop this 3D printed skull aquarium decoration into your tank and suddenly your fish are living their best gothic pirate life. Whether your betta is dramatically swimming through the eye socket or your shrimp are throwing a tiny house party inside, this skull fish tank cave is equal parts creepy-cool and actually useful. It sits right on the substrate as a centerpiece and doubles as a legit hide shelter for fish and shrimp.
📐 AT-A-GLANCE SPECS
• Size: 4.44 x 5.91 x 5.24 inches (112.87 x 150 x 133.22 mm)
• Material: PLA+ (plant-based, BPA-free, non-toxic filament)
• Finish: Matte, charcoal-gray-style texture with visible layer lines that give it an awesome rugged, bone-like character
• Style: Realistic-organic human skull — hollow eye sockets, nasal cavity, segmented teeth rows, and cranial suture impressions
• What's Included: 1 x 3D printed skull aquarium ornament (skull body + detached lower jaw resting in open-mouth position)
• Made to order in Riverview, FL by Derek using a Bambu Lab printer
✨ WHY THIS SKULL SLAPS
• 🐠 FUNCTIONAL FISH HIDE — hollow interior openings let fish and shrimp slip inside for shelter, stress relief, and natural hiding behavior
• 💀 SERIOUSLY DETAILED — suture line impressions on the cranial dome, individually segmented teeth, and deep recessed eye sockets make this look way more dramatic in person
• 🌱 AQUARIUM-SAFE MATERIAL — printed in PLA+ (plant-based plastic derived from corn starch, BPA-free, non-toxic) so your aquatic crew stays happy and healthy
• 🎨 YOUR COLOR, YOUR VIBE — available in 10 colors so you can match your tank's whole aesthetic

Pick your skull's color when you order! Available in:
• Black
• White
• Gray

Not sure which to pick? Black is a classic for that dark aquarium look, White gives serious deep-sea vibes, and Purple or Pink are super popular for planted tanks. Just leave your color choice in the notes at checkout!
🐟 HOW TO USE IT
• Rinse under cool water before placing in your tank — quick and easy
• Set it directly on the substrate (gravel, sand, rocks — whatever you're working with)
• Works as a centerpiece OR tucked in a corner for a more natural hide
• Position the detached lower jaw open-side up or angled for different looks
• Great for: betta fish tanks, shrimp tanks, community freshwater tanks, reptile terrariums, and desktop aquascapes
👥 WHO'S GONNA LOVE THIS
• Betta fish parents who want their tank to match their gothic energy
• Shrimp keepers looking for a fun new hide that actually looks cool
• Aquascape hobbyists hunting for that dark, dramatic centerpiece
• Pirate or skull-themed tank builders
• Anyone who thinks their aquarium deserves a personality upgrade
• Awesome gift for the fish nerd in your life — they will absolutely lose it
⚠️ CARE & HANDLING
• Safe for freshwater environments — rinse before first use
• PLA+ can soften in very warm water (above 140°F / 60°C), so no boiling to sterilize — just a gentle rinse does the trick
• Do not place in direct sunlight outside of water for extended periods
• The layer lines you see are totally normal for 3D printed items — they add character and a handmade feel!
• Not recommended for saltwater tanks (salt can affect PLA+ over long-term use)
📦 SHIPPING & PROCESSING
• Made to order — allow 2-3 business days before it ships
• Ships FREE to your door
• Carefully packaged so it arrives safe and ready to drop straight into your tank
🤝 SHOP PROMISE
Every piece is printed by a real person (hi, it's Derek!) who actually cares about the quality. If something's wrong when it arrives, reach out — we'll make it right, no drama, no runaround. Your fish deserve the best and so do you.
