How Do You Get Little Fish Icons (the Ones Below The Pics And Stuff)

[bettachick49]

Hello I have been a member for a couple of days, but I was wondering how you get the little yellow fish icons below personal pics, you know the ones that say newbie and stuff like that. Do you have to earn them or is it by how long you are a member? Thanks
