Thanks to PVAS member David McGrew. Contrary to the narration, these are bullheads (an Ameiurus species), not channel cats. Channels have a forked tail, while bullheads have a square tail.

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.
