Here’s my little Future Addicted Reef Tanker aka my little FART! He loves to sit and watch the tank and it can calm him down when he’s having a fit. Setting up a bigger tank in the living room so he can see it all the time instead of having to go into the back room of the house.
It's been shown that observing an aquarium a can lower stress and blood pressure, which is why you often see a tank in doctor's offices, etc. Makes sense that it should work for the little guys too
