A new modified version of our 30 L swim tunnel, with a motorized transparent belt that can be operated independently of the water flow, is now available.

We call it a Treadmill Swim Tunnel, and you can use it to force-exercise walking fish like rays or gurnards, crustaceans like crayfish or lobster, and other benthic animals at various speeds.

The moving floor is made from transparent food-grade rubber material allowing filming from below, and the planar lid and wall surrounding the test section also allows for filming/viewing from the top and left side.

The water flow can be adjusted independently from 5-175 cm/sec as for our standard 30 L swim tunnel, by means of a second motor and control box.
