Fish Feeder for Tank / Aquarium for Tubifex, worms

Tubifex / Worm / Multi Fish Feeder – for Acrylic or Glass Tube (13mm OD, fits 1/2 inch tube!)

I couldn't find any truly stylish or visually appealing live Tubifex feeder designs on Makerworld. Most existing models are quite basic and purely functional, which inspired me to create something both practical and attractive for aquarium enthusiasts.

This feeder is designed for easy live food dosing using a clear acrylic or glass tube with an outer diameter of 13mm (1/2 inch can be used!). Simply push the feeder holder onto one end of the tube, place it into the tank, and the tube remains nearly invisible in the aquarium. You can easily refill food from the top which sinks down.

By using tubes of different lengths, you can reach fish swimming near the bottom or feed specific areas, so all fish get a chance! For example, I used this method to feed my Dario dario in the lower area, without the Neon tetras snatching everything first.

The feeder is suitable for Tubifex worms, but feel free to use other foods!

Have fun printing and please share pictures of your aquariums with the acrylic Tubifeeder. Feedback welcome!

Just ask if you need other dimensions or another holder, I can upload these.

Use food-safe filament!

Tubifex / Multi Fish Feeder – for Acrylic or Glass Tube (13mm outer diameter, also suitable for 1/2 inch tube!)

Unfortunately, I couldn't find any truly beautiful or aesthetically pleasing Tubifex live feeder designs on Makerworld. Existing designs are often very functional and simple, which motivated me to develop something both practical and visually appealing

This feeder is perfect for the easy dosing of live food using a clear acrylic or glass tube (13mm outer diameter, also suitable for 1/2 inch tubes!). Simply push the holder onto one end, place it into the aquarium – the tube is almost invisible and can be refilled from the top

With different tube lengths, you can specifically feed fish at the bottom or reach certain areas in the aquarium. This way, all fish get food! For example, I feed my Dario dario at the bottom this way, without the Neon tetras eating everything first

The feeder works for Tubifex worms, but also for other fish food – feel free to try different variations!

Have fun printing, and show me your aquariums with the acrylic Tubifeeder. I would be very happy to receive feedback and pictures!
