The biggest one is 12,000 gallon, the smallest is 90ish.
The 12,000 has schools of yellow tangs, rays, clownfish, green chromis, variety of angels and many more.
There's a tank full of of jellyfish too.
There is no way they pump in ocean water, as we live in the middle of the country.
I have no clue on filtration, but I assume it's nice.
