Hi, im building a 180x150x50cm (350 gallon) tank, I know its really weird dimensions but it is being made to fit in a space and also I like the really wide look. I know the tank is large enough by volume but there is only 6 feet on the longest side. Aquascape is minimal with coral bommies to allow fish to swim alot. People say that this fish needs around an 11 foot tank but if you use jay hemdal's article "Estimating the Need for Swimming Space for Aquarium Fishes" it says to use the total swim room so that would be 180+150 = 330cm or 11 feet, let me know what you think.
