65 gallon aquarium possible Camry

[Dev795]

So i recently bought this 65g aquarium, currently cleaning it up...does anyone know what this little hole is used for?? Never seen a tank with one before ...i believe the tank is a Camry?

I believe that Camry Aquatics is an Asian brand. I can't see the rest of the tank in the picture, but I expect that you have an internal overflow that drains to a sump and then the hole is for the return line.

It is an overflow and me personally- I would utilize it as an access for a float for an ATO unit !!
Or you can plug it with a plastic plug from Home depot
