I am building a 880 gallon tank that is 11ft*40in*40in and have a stocking plan, but wanted to check with you guys first. What do you think about 5 hydrocynus vittatus, 3 kelberi, 3 monoculus , 1 jardini arowana, 1 ray, and 2 payara? Do you guys think it will be over stocked, under stocked, or just right?
