Question!

I seen some nice arowana tanks that are super clean and have no wires hanging into the fishtank or power filters(hob) hanging in the back. How do they achieve that simple and clean look?

ppl do a lot of stuff, like the do hidden in and out pumps and for the heater, if they got a big tank some ppl use like 60 gal tanks as filters or something, and they put the heater in the 60 gal filter, so its not in the tank but the heat still get transfered. umm some ppl got under ground filters. theres a lot of ways.
