Everybody loves aquatic plants! Come score some great deals this Sunday!🌱🐟🐈

Our June meeting is Sunday, June 7th, starting at noon at the Moose Lodge, 16411 NE Halsey St, Portland, OR 97230.
There will be no speaker this meeting as we will be conducting our annual plant auction…yep we decided we are just nuts enough to do it again.
In addition to the plants that will be auctioned by the club there will be the standard BAP/HAP items that will precede the club/donation portion of the auction.

If you are a member and have items you wish to auction off items, please note we are limiting non-donation items to four. No exceptions will be permitted.

If you are a non-member we are only accepting donations for this auction.

Finally please note that only fish/inverts/plants are allowed in the general auction. No hardscape, equipment, or tanks will be allowed due to the expected size of the auction. Again no exceptions.

Come join Sunday May 17th for our monthly meeting. With Mother's Day this weekend we are holding our meeting and auction the following Sunday the 17th at our normal time (noon) at the Moose Lodge.

Dean Tweeddale (Master Breeder Dean) will return to GPAS to give his new presentation titled “Dean’s Fry System and Beyond”.

Dean is a master breeder with over 60 years of experience in the aquarium hobby. He began with guppies, advanced to discus, and has since bred countless species of freshwater fish—virtually any species he could get his hands on.

Always an innovator, Dean, throughout his fishkeeping career, has built three in-house fish rooms and developed an incredible fry system. Some of his proudest moments in the hobby are developing a system to raise discus artificially, breeding many rare dwarf cichlids, continuous spawning of German blue rams, and spawning several L-number plecos. He has also traveled to Peru on multiple occasions and bred many of the wild fish he collected.

Dean is a familiar face in the online fishkeeping community, having appeared on numerous YouTube channels including Aquarium Co-Op, Tazawa Tanks, KeepingFishSimple, L.R. Bretz’s Aquatics, Swhiskey, Aquarist Podcast, Bentley Pasco, Harlan Ford, Friday Fish Facts, and Dustin’s Fish Tanks. He has also shared his expertise as a featured speaker for aquarium clubs across the country. Dean is passionate about inspiring others to experiment, innovate, and become the best fishkeepers they can be.

At the conclusion of his talk Dean will be available for a Q & A.

Come join in for April's monthly meeting this Sunday! 🐟
Nick Bertrand will be giving the talk: Wild
America: Western Fishes of the United
States, Tall tales and Forgotten Gems. This
talk focuses on some of the oddities found
in the aquatic parts of the American West.

Nick Bertrand is a supervisory fish
biologist and Portland District Chief of
Fisheries for the United States Army Corps
of Engineers. When asked how he became
a Fish Biologist, he always describes
keeping aquariums in high school as the
event that settled his many diverse
scientific passions on the singular one that
would never bore him, ichthyology.
Aquariums entered Nick's life when his
father decided he wanted one like he had in
his parents house. No one was prepared
for where this would go. At some point
during selecting fish for this tank anc
having it successfully cycle with Zebra
Danios, Nick discovered the magazine
Tropical Fish Hobbvist. At a time when
internet communities were still at best
forums and maybe myspace existed, he
tore through every copy of TFH he could
read and the love of fish behavior and
many ways evolution shaped their forms
would occupy him every after.

Being limited to only his own bedroom,
Nick mastered the multiple 10 gallon
planted tank set up. The space limitation
and exceptionally hard water of San
Antonio TX led him to many successes
with Livebearers and eventually joining the
American Livebearers Association
Membership in the ALA led to employment
at the XIphophorus Genetic Stock Center
and recruitment into graduate school at
Texas A&M Universitv. After Graduate
School, Nick began working for the US
Forest Service in Wyoming, then the
University of California at Davis in a fish
evolution lab. Then he would return ta
federal service with the US Fish and
Wildlife in Roswell NM working with
western desert fishes in a genetics lab and
hatchery. He would then return to
California to work for the Bureau of
Reclamation as their lead Delta Smelt
Hatchery Biologist. It was moving on from
that position to Portland that led him to a
Greater Portland Aquarium Society swapmeet where upon learning he was a fish biologist, he was immediately recruited to speak.

Please join us for our next monthly meeting, where we will be welcoming Meretta zufuto!

Maretta Zufuto will speak about “The Selective Breeding in Betta Splendens”.

Maretta has been keeping fish since 2019, gradually expanding from small personal setups and posting on social media into breeding, importing, and selling fish online.

Between 2021 and 2023, she focused on breeding both domestic and wild bettas while also importing shrimp and other nano species for her website. In the spring of 2023, her part-time betta retail business began to grow, and she was able to stop school and run a full-time business.

In July 2024, PNW Bettas opened a retail aquarium store in Corvallis, Oregon, where she has a full array of freshwater aquarium fish, inverts, and products. She stocks a lot more than just bettas but focuses on nano fish and, of course, a larger betta selection.
