unfortunately for the whims of finances and time, the tank wont arrive for quite a while, like 6 years or more. but time flies so what can i say. i think ive decided that this tank will be a ray only tank, to ease the stress on them and enhance my stocking options. ive talked to the guy that im looking at getting the tank from, he quoted a much cheaper tank with the same footprint but 4 inches shorter for 1500 dollars less, due to the acrylic thickness and what he had in stock atm. so the tank will probably be 800 gallons, but the same footprint. shouldnt make much difference? im gonna keep my silver arowana in a different tank. and if i decided to get an arowana for that ray tank, maybe by that time they will have lifted the us importation of asian arowana, a very docile tankmate. thanks for the help nic
