Not Veterinary Advice
KnowBetta provides general information about betta fish care based on published research, veterinary references, and personal experience. This site is not a substitute for professional veterinary advice, diagnosis, or treatment.
If your fish is sick, consult a veterinarian who treats fish — especially for serious conditions, persistent symptoms, or anything involving medication. We do our best to cite reliable sources, but every fish and every situation is different.
Our Sources
Articles on KnowBetta cite peer-reviewed research, veterinary textbooks, and established care references wherever possible. Source lists appear at the bottom of each article. We try to be transparent about what the evidence says and where it’s thin or conflicting.
That said, fishkeeping science evolves. Something we recommend today could be revised as new research comes out. We update articles when we become aware of meaningful new information, but we can’t guarantee that every article reflects the absolute latest findings at all times.
Amazon Links
Some articles contain links to products on Amazon. These are not affiliate links — we don’t earn money when you click them or buy something. We include them as a convenience so you can see the specific products we’re referring to. We’re not paid or sponsored by any brand.
If that ever changes, we’ll disclose it clearly on this page and within the relevant articles.
Accuracy
We make every effort to ensure the information on KnowBetta is accurate and well-sourced. If you spot an error or disagree with something we’ve published, please email us at [email protected]. We take corrections seriously.
Liability
KnowBetta is provided “as is.” We aren’t liable for any outcomes resulting from following advice on this site. Fishkeeping involves judgment calls — water chemistry, tank mates, medication dosing — and the responsibility for those decisions is yours.
