Paluweb videos

This page features some cool videos from my paludarium, from lighting tests to feeding the foureyes!

Feeding the FourEyes

The FourEyes are actually Anableps anableps fish or more popular named four-eyed fish. These fish are so much fun! As the only species of fish I know to be able to see clearly above water, they are very responsive to things happening above the water:

Lighting tests

The paludarium lighting is an automated art in itself. The next video shows all the lighting abilities of the first version of the paludarium. It includes dusk & dawn, lighting and many other things:

Recently the first real thunderstorm hit the Paludarium 2.0, with sound and all!

  1. Hi, can I find more details on how your built your lighting system / controller?

    I’m in the planning stage of a large paladarium and would love to build a similar system.



    • Hi Chris,

      There is some information available on my older website ( Unfortunately that website is in Dutch… There are no real down ‘n dirty details there, as there is SO much to building something like this. Most people who want to start building get themselves an Arduino kit ( These are pre-built controllers that use the same sort of controller as my controllers do. You could have that Arduino time and control everything, there is a lot of info available around the programming of Arduino’s.

      Another option is using a Raspberry Pi. These are Linux boards, but they too have some I/O features to control hardware directly, although I am not so sure they’ll be able to for example dim light sources in hardware.

      I myself use homebuilt boards that are based on really small Atmel AVR microcontrollers. Each board controls four PWM outputs, that are used to control 4 leds, fans or pumps each. All controllers sit on a RS232-like serial connection to form a very simple single master-multiple slaves network. In turn, I use a full blown PC (running Windows server 2003) to run an application that controls the controllers (still following??). This application sends setpoints to the small controllers every 30 minutes. The small controllers in their turn just do all the work to slowly regulate the light sources to their setpoint.

      As you can see, there are several ways to get things working. I used a lot of controller boards because I wanted each light source individually controllable. But nothing is stopping you from controlling all light sources from a single controller if that is enough trouble for you 🙂

    • As for the lighting system, you can find SOME info although not all unfortunately (I hope to add this in the future as I build stuff up again). Some info sits here:

      and of course here:

      No real tech details though. I have had several requests from people wanting to build just the same thing. But that is really complex, the best change is using something like Arduino boards that you interface to a small PC (or run from only arduinos and make one “master”). I may post the dirty tech details, like how I communicate between MCUs (I use the same series of MCUs as the Arduino’s, but it is all built from scratch).

  2. Hey Erik!

    What is the rain system you have set up? What kind of filtration do you use?
