Introducing the Keystone Clash
Hundreds of aquarium hobbyists will show their prized fish at the Holiday Inn of Morgantown, PA on September 26-28, 2025. This is the best place to see, show, buy, and appreciate fish and aquariums.
The Keystone Clash, now in its tenth year, has been a collaborative effort between the Cichlid Club of York (CCY) and Aquarium Club of Lancaster County (ACLC). Please note that this event serves as a fundraiser for the two clubs, and as such, all purchased items are non-refundable.
