Long horizontal air pump? Equipment advice needed

Searching through amazon feedback I saw a photo of a pretty lovely tank with what looks like a horizontal air pump. I tried to search that on amazon but can't find anything but would really love one for my fish tank. Could someone please tell me what's the name of that thing or where to find it?

Pretty please

Photo attached, it's the blue thingy at the back. I don't care about the colour, just like the bubbles

That device is just an air stone that is hooked up to a air pump via a tubing.

I will sound daft here but is it something I can buy or do I need to DIY it?

Thank you very very much, I love you! (in a fishy way)

PS: props for the smile part of amazon link!
