Definitely one of the biggest electrical nightmares of my life and I've wired entire homes and commercial buildings. Mostly because of how tight it is. Every circuit is metered. There's an overall circuit for the entire system in the bottom circuit is on timer wired to a relay so it can run in reverse so you have a feeding timer.

Makes you wonder how these things have survived for millions of years?

Got a couple baby ricordia's starting

I always love watching these little guys.
