This tutorial demonstrates how to install and use the brass feeder mechanism, on the Zantiks AD or LT units, which is used to feed fish. It is important that the Zantiks system has first been shutdown from the control console page, then after waiting 10seconds remove power to the Zantiks top box before connecting or removing the motor cable to/from the motor.
Set up
Installing the brass feeder
The brass feeder mechanism can be attached to the motor and stand with the use of the hex key driver. The video below illustrates how to install the brass feeder.
Setting up the brass feeder mechanism for fish on the Zantiks LT
The brass feeder mechanism holds and delivers food for fish. The food commonly used in the UK for zebrafish is the ZM400 (size range 400-600 microns) from ZM Systems. We have also used Zebrafeed 400-600 from Sparos, and this is available worldwide (inc. in US, from Techniplast). Other similarly sized, slow-sinking fish food that does not become sticky will work reliably for fish reward.
NOTE: There is a different pellet delivery feeder for mice & rats. You may also set up the motor platform with the peristaltic pump for liquid delivery. See the Peristaltic pump demo.
Script Explanation
This demo script shows how to use the feeder mechanism. There are two commands for the feeder:
FEEDER(1) - rotates the mechanism until the divot is in position to drop solid food.
FEEDER(0) - activates a “fake feed”, which will create the noise of the feeder, but the mechanism does not rotate enough to drop any food.
You will hear and see the feeder turning when you run this script.
