Missouri Aquarium Society welcomes anyone with an interest in aquatic life, from fish to plants. Our members range from beginners to published experts, and we welcome families and children. Please come to a meeting or two as our guest. We will enjoy meeting you!

Meetings are held at Dorsett Village Church, 2240 Bennington Place Maryland Heights, MO 63043 (Map Below)
on the third Thursday of every month, at 7:30 PM.
Families and spouses of the fishkeeper are welcome as well.

Our monthly get-togethers begin with a short business meeting then a speaker / program, followed by door prizes, a mini auction, refreshments and raffle. Past programs have included everything from presentations by internationally known speakers and authors, to educational and fun "fish fact" games.

We have a monthly "bowl show" where members show off their prize fish.

Our Horticultural and Breeders Award Programs are very active, with members bringing in fish and plants they have raised. These specimens are included in our monthly mini-auctions.
