A racetrack aquarium is an aquarium that has the same shape as an oval tank but the only difference is that a racetrack aquarium has a oval shaped pillar in the center.What's the difference between a racetrack aquarium and an oval aquarium?
Yes, the overflowIf by "pillar" you mean overflow...most real tanks have them lol...it being square or oval has nothing to do with the tanks shape or name.
