Aquarium Advice Addict
For the fish I keep footprint is far more important than gals
People always as is a 150 or other sizes large enough for rays
If the tank is very with but only 8" tall then yes it may be large enough
But if it's very tall but only 8" wide then no it's to small
This is why have always said you can't go on any chart app or rule when stocking a tank as many factors come into play only the owner know if it's overstocked by looking at it and doing water tests
No one has the right to say a tank is overstocked or not fish keeping is a learning game we lean from our time in the hobby and with people flaming people all the time I don't feel it helps
This wasn't all directed at you just the footprint comment
Footprint directly means the length and width of an aquarium but has no bearing on the height. I.e. a 75g aquarium and a 90g aquarium have the same footprint. Both are 4ft long and 18in. Wide. Subsequently their stocking levels are the exact same on aqadvisor.
Aqadvisor uses a general rule of thumb to give points to fish based on their size and approximate bio load as well as number of different species and gives a percentage of how full the tank is. It's about as good a system as can be expected.
