Color is important to fish. It’s used for camouflage, mate selection and defense. While easily seen in tropical aquarium fish, our native fishes also have special colors.

🦀 Did you know that horseshoe crabs shed or "molt" their shells in order to grow bigger? Each horseshoe crab molts about 16 to 17 times before it reaches maturity. If you find a horseshoe crab shell on the beach, you can tell it's a molt and not a dead animal if it's light and there is an open slit at the front. The slit is where the horseshoe crab exited from its old shell.
Come visit the aquarium to see horseshoe crab molts of all sizes—from tiny pale yearlings to large adult females. Yup, females are bigger, by about 1/3! 💪🏼

Lots of cool livestock in our Fall Auction, Sunday, October 3, at 10:30 a.m.
The Potomac Valley Aquarium Society was founded in 1960 for the purpose of furthering the aquarium hobby by the dissemination of information and advice, and the promotion of good fellowship among the members by organized activities and competitions.
Our club meets every month the first Saturday of the month except for the Spring and Fall All-Day Auctions which fall on Sunday. Sometimes the dates, like the July Bowl Show, are pushed to avoid a holiday so always check the Program.
Meetings are free and open to the public. People who attend more than one or two meetings per year are asked to join the club. The annual membership fee for individuals is only $20/year and helps us pay for the meeting room.
