i don't understand why the blue is bigger than the yellow and they say you need 55 gal for blue and 75 for yellow and the blue gets two inches bigger.is the blue less active?the store i go to has a baby blue but they told me they get diseases easy
How old is the marine book? If it is old, then it could be outdated information. If it is recent, then it is flat-out wrong. A Blue Tang cannot live in a 55 gallon tank, and a Yellow Tang should not be in a 75.why do the marine books give those gallon recommendations
