What's the most important primary source on betta genetics?

The 2020 chromosome-level genome assembly (PubMed 32385046) and the 2022 genetic-architecture paper (PubMed 36129976). Between them they cover the reference genome and the major phenotypic loci.

Where do I check IUCN conservation status?

iucnredlist.org directly. Each species has its own assessment page with population trend, range, and threat codes.

Is Seriously Fish reliable?

Yes, for species profiles. Community-maintained, accurate on taxonomy and keeping requirements. Primary source for many wild-betta identification questions.

What's the best veterinary reference?

Merck Veterinary Manual for general disease treatment. University aquaculture extension publications for species-specific welfare research. Peer-reviewed journals for recent findings.

How to use this page

When a claim on Betta Dreams matters for a decision you’re making (medication dosage, conservation assessment, tank size justification), follow the source to verify current status. This page is updated as new primary sources emerge.

If you’re writing your own betta content, cite these directly. Don’t cite a secondary source when the primary is accessible.
