Randy Carey, our resident Characin expert, spoke at the Seattle club meeting last night. You can see/hear his talk at https://www.youtube.com/watch?v=83WJHsF2WXA. The video will only be available for 1 - 2 days, before the Greater Seattle Aquarium Society takes it down and made available only to their club members.
You can forward to the 4:58 mark when the video actually starts. Club activities go through 12:30, when Randy starts his presentation on tetras and barbs. Enjoy!
