The Northeast Council of Aquarium Societies (NEC) celebrates its 50th year of service at its 31st annual convention, April 7-9, 2006 -- including *An Evening with Aquarium Legends*.
 
Read the speaker list, then download the registration form, and get set to join the fun at what promises to be the year's biggest tropical fish convention.

And while you're there, attend the AGA's annual meeting Friday afternoon (2-4pm). This year's speaker is Claus Christensen, Tropica's Managing Director.
