I have a 47 gallon tank that's about 50% planted. I have 5 Giant Danios, 6 Tiger Barbs, 6 Green Cory Cats, 7 Otos, and 3 Zebra Nerite Snails. Going by the "inch per gallon" rule, it would seem that I have overstocked, but I am only 70% stocked according to aqadvisor.com. Any thoughts? My filter is driven by a pump rated at 480gph.
