Don't think it would be that much. Even Arapaimag doesn't spend that much a week with some 70k gallons added upHow much would all these tanks cost to maintain? I'm gonna guess somewhere around $5000 a week. This would be an awesome fish room! Lmao

Electricity and water costs would depend on where you live. Food is quite cheap, if you feed the right stuff, buy at the right places and if you buy in bulk. Filters can be made DIY and for heating you could use your houses central heating system. So probably wouldn't be 5000$, although you would stil be spending a lot.
