Why Researchers Turned This Goldfish Into a Cyborg

Interesting study about how fish navigate. Worth getting past the curiosity gap headline and the rambling lead.

Neuroscientists are examining how fish navigate their world using different brain circuits than those relied on by mammals like us.

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.

Happy National Volunteer Appreciation Day! 🥳

We’d like to thank our volunteers who help us in ways big and small: Educating visitors, manning the touch tank, wiping sticky fingerprints off the tanks, and scooping p**p! 🤓 🦐 🧹 💩 It all needs to be done, and we’re grateful you do it so well.

MIT researchers work on repelling the bane of tropical-fish enthusiasts: Algae growing on the glass of their aquariums, but with the goal of reducing carbon emissions

https://www.universalhub.com/2023/mit-researchers-work-repelling-bane-tropical-fish

MIT News reports researchers may have figured out how to keep algae from growing on glass surfaces: Coat the glass with "a material that can hold an electrostatic charge, and then applying a very small voltage to that layer," which in turn repels the algae, which have a negative charge on their cell...

🦀 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! 💪🏼

Our Story

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.
