October 8th: Dr. A.I. Mazeroll "Fishes of Cambodia" (Rescheduled)

October 8th, Otto Miller Hall, 7:30 PM

The snow got us back in February, but we rescheduled! Our October meeting's presentation is Fishes of Cambodia - Hidden Gems, presented by Dr. Anthony Inder Mazeroll. He describes the talk as a photographic guide to the fishes he encountered in different habitats in Cambodia.

Dr. Mazeroll is a professor of Biology and Environmental Studies at Soka University of America. He has been keeping fish since the age of 8, and currently has a 2-car garage converted into a fishroom, as well as a 500-gallon Peruvian Amazon biotope tank in his living room. He divides his time between Southern California and Peru, where he is the executive director of the Amazon Research Center for Ornamental Fishes in Iquitos.

Meeting starts at 7:30 PM, 6:30 social, with traditional monthly auction to follow.

Home Show 2020 is now open for registration at

It's simple: Six of us, a videographer, photographer, Chair, and three judges, come to your house for about 30-45 minutes on the weekend (not the Super Bowl). You show off your tanks and we ask questions. The GSAS Home Show is open to all members, from I've just got one, to I have a fishroom. Everyone, including you! Results are shown at a meeting in the spring.

Did you participate in one of the workshops at last May's AGA Convention? Or did you win a tank in the auction or raffle? We would like to come visit!

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