Interesting Facts from the Academy of Sciences
Clown fish
Fact
The Clown anemonefish’s immunity to its host’s venomous sting is not a genetic trait. Instead it is acquired slowly by acclimation. The fish will initially take several approaches, each time rubbing the anemone’s stinging tentacles on specific parts of its body. After several of these interactions the fish will be immune the venom. However, this immunity is not permanent. If the fish leaves its host for too long, it will lose the immunity and have to restart the process.

Emperor angelfish
Fact
The Academy only has one Emperor Angelfish on display, Mr. B. This is because Emperor Angelfish are highly territorial. If Mr. B was in the Coral Reef Tank with another angelfish, the two of them would fight to the death. Recently Mr. B had to be moved into the top portion of the tank due to his habit of eating our coral, which does not grow fast enough to replenish itself after his meals.
