I Built a Secret Room in a Fish Tank

This week, I’m building a Secret Room with a Super Secret Surprise. A huge thanks to my friends at Seachem for making this possible.

This fish tank and secret room was the most difficult and most expensive build yet! The hidden wood secret room and the custom acrylic dome took weeks to design, build and finish. The end result looks amazing and is so awesome in person!

The aquarium holds over 90 gallons of water. The secret room gives an amazing view of the schooling fish above when you put your head up and into the dome. I want to make an even bigger secret room in the future, comment below if you want to see this!

Quick question. Does your cat ever try to eat your pet fish? Or does he know not to because you love them?
