  1. Corydoras in Theory and Practice

    • Fri Sept 22, 1 PM - 2:15 PM

  2. The World of Apistogramma

    • Sat Sept 23, 2:30 PM - 3:45 PM



Already in my youth I had my first contacts with aquaristics through my parents. At about 10 years old, I got my first own aquarium and started to gain my first experiences with this exciting hobby. In the 1990s, due to my studies in mathematics / computer science and the founding of my IT company, other things came to the fore. However, I returned to the aquarium in 2002.

After the first beginnings in the Usenet newsgroup de.rec.tiere.aquaristik (d.r.t.a) I developed my social network of aquaristic acquaintances and friends more and more. For years now, I have been a member of the German Cichlid Society (DCG), the VDA Zwergcichliden (AKZ) and the International Community Barben-Schmerlen-Salmler-Welse (IG BSSW), or their predecessor, the BSSW working group in the VDA.

My interests are clearly in the underwater fauna of the South American continent, especially in the dwarf cichlids of the genus Apistogramma and the Harnischwelsen. In the meantime, I have cared for more than 25 different Apistogramma species, most of which I could multiply. My biggest passion, however, are the catfish and especially the genus Panaqolus, of which I currently hold about 10 species and increase.

In 2008, for the first time, I had the opportunity to experience my fosterlings live in the wild. I traveled with some friends to Suriname and the Brazilian state of Roraima. Meanwhile, I also went on expeditions to Peru, others to Brazil and with the company JBL I accompanied as a guide a tour group to Venezuela.



  1. Building a Backyard Biotope

    • Fri Sept 22, 10:30 AM - 11:45 AM



Jen's first aquarium, acquired at the age of seven, housed a humble mix of guppies, barbs, tetras, then cichlids through the years. As an adult, she discovered the much bigger world of fishkeeping via a most fateful encounter one afternoon involving a Craigslist ad, former Army Lieutenant, mention of Takashi Amano, and suggestion to attend a club meeting. One club meeting later, the much bigger world of local fish clubs, planted tanks, and full-fledged aquaphilia had captured her. Ever since that first GWAPA meeting, Jen has been a passionate aquarium hobbyist and a dedicated enthusiast.

Currently she keeps and breeds an eclectic assortment of fish, with a recent love for biotopes and native fish, and actively competes in aquascaping competitions both live and virtual. Jen has served on the board of the Greater Washington Aquatic Plant Association (GWAPA) since 2007, in addition to serving as an Aquatic Gardeners Association (AGA) Board Member since 2015. As an aquascaper, Jen is the most decorated in the US for live events, and since 2008 has won numerous awards in competitions at Aquafest, Aquamania, the Big Fish Deal, The Aquatic Experience, and Aquashella. She has also competed in the IAPLC and AGA online contests with a highest international ranking of #224 in IAPLC, and “Top Five” on two occasions in AGA. Jen is also an official Ambassador for Oase, a German-based filtration company, and represents them at tradeshows and store demos across the US.

Outside the tank, Jen holds a degree in Graphic Design and runs her creative business, Jen Will Design, from her home in Alexandria, VA, just outside Washington, DC.

Eager to grow the hobby in the US, Jen enjoys traveling to events and clubs nationwide to give presentations, aquascaping demos, inspiration, and encouragement to future ‘scapers.

  1. How to Ship Fish so they arrive Alive 99% of the Time

    • Fri Sept 22, 6:15 PM - 7:30 PM

  2. Building a new kind of Fish Store

    • Sat Sept 23, 10:30 AM - 11:45 AM


Biography: Dan Hodnett is the founder of, a company on a mission to improve the aquarium fish industry. His goal is to be the store a fish would choose to go to if a fish could choose which fish store it ended up at. To this end, he built a state-of-the-art retail facility where fish receive "spa resort" pampering before they are sent to customers via uniquely humane shipping practices. The final result is that almost 99% of fish sold arrive alive and stay alive for customers. Here at the Keystone Clash, Dan will be sharing the details of his company's facility,
processes, procedures, and mindset in the hopes that others will experience the same success and that our aquarium fish will enter a kinder, gentler industry and hobby.

Dan is a fish breeder at heart. Since he began keeping fish in junior high, he has bred and raised hundreds of species from many fish families. His favorite fish remain the ones he started with...the killifishes.
