8. Sample from a variety of aquaria:
freshwater, marine, fish, plants
Collect from KWAS members, extract DNA, quantitative real-time
PCR for ammonia-oxidizing archaea (AOA) and ammonia-
oxidizing bacteria (AOB).
Fingerprinting and sequencing for diversity.

14. UNANSWERED QUESTIONS
What aspects of water chemistry shape
aquarium AOA (and AOB) communities?
Do AOA/AOB communities correlate?
Does AOB/AOA biofilm succession occur
when aquariums are first established?
From where do filter AOA seed populations
originate? Do they seed homes (“x”)?
Do AOA buffer aquaria from
ammonia toxicity during antibiotic
treatment?
15. ADVANTAGES OF AQUARIUMS
FOR CITIZEN SCIENCE
Aquarium hobbyists are organized by
societies, pet stores – already networked
Young people are involved and invested
(children, schools, undergrads)
Individual results matter to aquarists
Aquaria are aquatic microcosms,
“experiments” – already citizen science!
Standalone or accessory to existing
“Domestic Biome” initiatives
High biomass, easy sampling
