I love researching fish and today I looked up Clownfish. I learned an interesting fact (of course most people already knew this! :oops:)
At birth, all Clown Fish are males and as they grow, the predominant male will become the dominate female which will give her the job of primary defender of the territory. WOW!

What is an interesting fact you know about a species of fish?
 
Fresh water aquarium sharks are not really sharks, they are types of minnows.
