ive got the tank at 26.5 celcius...
which according to the books is 2.5 over the maximum that a sturgeon can handle because then the water oxygen levels drop too low... but this guy is a good 16-18" and hes totally fine... but thats prolly cuz i have two flow pumps with and airpump hooked up to them that pumps 1700 liters of air an hour...
my oxygin levels are really high...
