1pcs Transparent Acrylic Pipe Aquarium Fish Tank U-Shape Connector Water Supply Tube, for Garden Supplies Home DIY Connector O.D 20~32mm (Color : Outer Dia 25mm)

I wished it would come in more variety sizes. It was smaller than I thought but worth the price

high quality and it’s super clear

Not what I expect

I bought this product for a female betta fish of mine. I had a 2.5 gallon tank sitting around and got her a 3 gallon to connect to via this tube. With the help of a 3d printed holder for it, it works great! It came way faster than expected and we'll packaged. Although a little warped no biggie. Funnily enough she ended up using it on accident to cross tanks and hasn't yet figured it out. The bigger size may be better but once she figures it out I'm sure it'll be fine. As always I will throw a little caution because fish will be fish and somehow get themselves stuck but so far I've had good luck!

Just a small tube

This is bent a warped around the curve. Looks melted.

exactly what i expected
