It is an aquarium created in March 2019.

Hi! I am Y.Tateno of Japan.
My nickname is yashichi.
In Japanese, ya = 8, shichi = 7, so I named my aquarium 87system.
In addition, I used 87 because I started marine aquarium in 1987.
At first I was thinking of naming it as 87reef, but I chose 87system for the purpose of widely introducing the unique self-made nano-system I am focusing on now.

When I post a lot of photos, it is difficult to scroll to see them, so I have classified them into several categories.
I hope you enjoy them.
