June 8th: Dean Tweeddale: Dean's Fry System

Saturday, June 8th, 1:00 PM (noon Social/Setup)
Dean Tweeddale: “Dean's Fry System”
SPU, Otto Miller Hall Room 109
Also: Informal potluck Friday June 7th 5:30~9 PM in North Seattle

Longtime GSAS member Dean Tweeddale has been in the hobby more than six decades, breeding discus, angels, plecos, cories, rainbows, and others. His fishrooms are sights to see! Dean currently maintains between 55-60 tanks ranging in capacity between two and 75 gallons. He sells between 200-500 fish every month, depending on his available time. The development and constant improvement of his fry rearing system is what he is most proud of, and the subject of his presentation this month.

Dean has been to Peru four times, collecting fish in the wild, bringing back 40+ species, and has successfully spawned about 75% of them.

Dean is very approachable with sharing knowledge --- in 2022 and 2023, he spoke at 23 clubs nationwide! GSAS is incredibly privileged to have Dean presenting again at the home club!

This is the last meeting of the season, and will include election of the 2024-25 board members. And don't forget our Monthly Auction at the end of the meeting (sellers, pre-register your stuff here).

Members, join us Friday evening (the day before the talk) for a backyard potluck gathering in North Seattle. This is an opportunity to just hang out with Dean and other GSAS members informally! RSVP to Mark at for directions and what to bring.
