Hi...We have a 55 gal
tank... I am trying to calculate if I can purchase additional fish. I obtained the following adult fish measurements from liveaquaria.com :
Percula Clownfish Adult size up to 3 in (2)
Royal Gramma Adult size up to 3 in (1)
Yellow Tang Adult size up to 8 in (1)
Butterfly Adult up to 10 in (1)
According to the calculator on this website, I can have 11 inches of fish excluding the tail. Are the above measurements including/excluding the tail? Please let me know what you think. I also have a chocolate chip starfish. Do starfish/snails factor in to the max load in an aquarium? If so, how do you calculate "fish inches"?
