About KeepersNook
Expert care guides for every keeper. Species guides, feeding safety, compatibility charts, and setup walkthroughs.
Why We Exist
The Care Guide Library We Wished Existed
We are Vinh Nguyen, and KeepersNook is the care guide library we wished existed when we started keeping fish in a 10-gallon tank ten years ago.
Back then, we made every beginner mistake in the book: unheated betta bowls, overstocked community tanks, feeding bread to goldfish. The information was out there, but it was scattered across forums, buried in academic papers, or wrapped in so much filler you would scroll for five minutes before finding an actual answer.
KeepersNook exists to fix that.
Every article follows the same principle: lead with the answer, then explain why. No filler paragraphs, no vague advice, no recycled forum opinions presented as fact. If we are not sure about something, we say so and point you to someone who is.

Founder & Lead Author
Ten years of hands-on fishkeeping and backyard poultry care, starting from a single betta in a college dorm and scaling to multi-tank setups and a flock of heritage breeds. Every guide on KeepersNook pulls from that decade of keeping — the successes, the losses, and the mistakes that taught more than any textbook.
- 10+ years keeping freshwater fish and chickens
- Freshwater fish specialist — bettas, tetras, cichlids, livebearers, catfish
- Chickens & poultry — heritage breeds, egg production, flock management
- Research-backed — every recommendation cites veterinary or university sources

Our Process
How Every Article Gets Built
Four steps, no shortcuts. Every article goes through the same editorial pipeline.
We pull from veterinary journals, university extension programs, and species-specific databases before writing a single sentence.
Every care recommendation links back to a verifiable source. You will see institution badges on every sources block.
If published research says one thing but ten years of keeping says another, we flag the discrepancy and explain both sides.
Articles are reviewed on a rolling schedule. Every page shows its last-updated date.
Transparency
AI-Assisted Content
Some of our articles use AI-assisted drafting as part of our editorial workflow. Every AI-assisted article goes through human review, fact-checking against primary sources, and editorial revision before publishing.
Our position: AI helps with research synthesis and first-draft structure. The keeper expertise, source verification, and final editorial judgment are always human. Our Editorial Policy explains the full process.
Trust

- Veterinary sources — care recommendations backed by veterinary journals, Merck Veterinary Manual, and licensed DVM publications
