October 11: Mark Duffill - Loaches

GSAS is proud to present Mark Duffill from Great Britain as our October speaker. Mark will be presenting on loaches, a fish we have never had the privilege of a full meeting's treatment!

Mark has a long history with the hobby. He primarily works with Loaches, Rasboras and other Asian species. He is the founder of the International Loach Association, has written books and worldwide magazine articles on the subject. He has spawned 20+ loach species (some considered unbreedable at the time). He comes to GSAS in the midst of a multi-club North American tour of sorts.

After the meeting, we will have our usual monthly auction, plus door prizes and other giveaways.

Thanks to our 2016 Auction Donors

A huge thanks to all the attendees and volunteers at our 2016 Big General Auction -- we sold a ridiculous number of items, and will be able to keep GSAS running quite healthily for the next year, including some speakers from across the country and even the ocean (hopefully no cancellations this time!)...

Please buy stuff from all the local stores and national companies that provided us with the huge variety of donations this year! We are really appreciative of their support.
