I'm leaning towards a white tip reef shark and a sting ray. And I am honestly not keeping up with the cost. If I need something I just buy it as I go along , so I really can't say how much I've spent so far to be exact There are cheaper ways to do this but to be honest I didn't decide to do this myself to go cheap ( no I don't have 80k to put in an aquarium either ) I wanted to do this as a project in my spare time to keep me busy and do it the right way. This tank is only temporary. When the shark gets bigger I'm going to build a tank 3xs this size
