If I were to put a samll tank on top of my existing, how could I get water to flow into it and back into the main tank?

I'd either use it to house a Betta, or use it to hold my Pothos....

Can I put a tube going in and a tube going out and then create a siphon? Or would it need to be pumped?

Thanks

To let water out of the tank above your either going to have it overflow or another pump.

why would it need to overflow? If the exit pipe was below water level then surely what is siphoned out would get pulled up from the main tank?
 
Tube A connects from main tank to tank above
Tube B connects from main tank to tank above

Siphon begins from one end and pulls water upwards, same as when you do your water changes you need the water to rise up and over the glass and then downwards....

A siphon does not have to go down 'all' the way

A quick google in hydroponics suggests this as a 'bell siphon'

Just need to know how to do it properly....
 
I think I understand what you are asking, but you would need a pump to elevate the water to the holding tank above your main tank. Water doesn't travel uphill.
 
You actually can get a pipe that goes over the tank wall and can siphon, it just needs to be primed, and both ends of the pipe must be submerged at all times with no other openings. theres a few threads on here about it in the diy section. People do that instead of drilling tanks for overflows. Only problem is without a gate or ball valve on the pipe you cant regulate the flow rate and its probably not going to match your incoming water flow rate
