Saturday November 10: Planted "Plus" (Fish and Drygoods) Auction

TL;DR: Saturday November 10th, 10AM, White Center Eagles. Plants, Fish, Drygoods!

For one year only, we are expanding our traditional November plant auction to include not only fish but also drygoods. Call it a Mini General Auction or a Planted Plus Auction. Whatever the name, it means one thing: lots of awesome aquarium stuff being sold by GSAS members, plus a generous selection of plants from Florida Aquatic Nurseries.

Because this is gonna be big, we are holding it on a Saturday morning, and we have also found a much bigger space than last year's plant auction: White Center Fraternal Order of Eagles, 10452 15th Ave SW, Seattle, WA 98146. It's super easy to get to from 99/509, and fairly close to I5 as well. Tons of parking right in the lots there, and no stairs. Lots of lunch options close (though we will have pizza slices available).

Bidding starts at 10 AM, preview and setup at 9. Please read the auction guidelines for more information. If you are a member, please pre-register your items. Also, if you have a large number of donations, contact auction chair Erik at

Non-members are always welcome -- spread the news, print and hang the amazing poster from Amit! Volunteer to be a runner or recorder for a stretch.

Hope to see our entire membership there on the 10th!

Home Show registration - still a couple spots open!

The Home Show 2019 has a couple spots still open for registration at

Want to show your tanks? One gallon to infinity; all are welcome!

It's simple: Six of us, a videographer (Erik), photographer (Steev), Chair (Mike), and three judges, come to your house for about 30-45 minutes on the weekend of February 9-10th. You show off your tanks and we ask questions. Results are shown at a meeting in the spring.

Categories for this year are still being decided, so the possibilities are endless for you to create... we could look for minimalism, maximalism, middle-ground, high tech, low tech, on-a-budget aquariums, fitting into the space (apartment, tiny house, etc).

If you'd like an idea of how much fun it is, see previous years here.
