Algae feeder for tang fishes

🪸 Algae Feeder for Tang Fishes

This Algae Feeder is a 3D-printed seaweed holder designed for saltwater aquariums. It allows you to easily feed nori or algae sheets to tangs and other herbivorous fish without the food floating away.

💡 Features:

• Simple and practical design
• Holds nori sheets securely in place
• Magnetic mounting system for flexible placement on aquarium glass
• Easy to print, clean, and assemble (no supports required)

⚙️ Recommended Print Settings:

• Material: PETG or ASA (recommended for saltwater use)
• Layer height: 0.2 mm
• Infill: 30–50%
• neodymium magnets works the best for higher glass thickness

⚠️ Important Note:

The magnets must be sealed to prevent rust or corrosion when exposed to saltwater.
I sealed mine with epoxy resin, which works perfectly and ensures long-lasting protection.
