About Fin & Filter

Fin & Filter publishes practical freshwater aquarium guides for beginners in the United States — bettas, community fish, and planted tanks. Our goal is simple: answer the question you actually searched for, in plain English, with information you can act on today.

How we write

Every guide starts from real search questions aquarium keepers ask. We research authoritative sources (aquatic veterinary associations, aquarium societies, university extensions), draft the guide, and then run it through a multi-step editorial review — fact-checking against sources, originality analysis, and plain-language editing — before anything goes live.

We use AI tools to assist research and drafting. Every published article is reviewed and approved by our editorial process, and we correct errors when we find them.

What we are not

We are not aquatic veterinarians, and our content is informational only. Water parameters and fish needs vary by species and setup. When in doubt, test your water and consult a local fish store or aquatic veterinarian.
