The visual field guide

Illustration
& image sources.

The publication uses credited photographs of real fish alongside original explanatory diagrams. Photographs are illustrative scenes, not our test tanks, clinical cases or proof of a care outcome. The retained digital habitat below was made with OpenAI image generation and is labeled as an illustration.

Original illustrated freshwater habitat
Inside the glass / original CGI-style illustration, November 2026. Bed geometry, pack diagrams and notebook illustrations are authored in code. The cloudy-water observation and porous-media illustrations are original conceptual diagrams. Planting forms, test vials, nutrient-role diagrams and filter-media comparisons are also original code-authored artwork. They do not diagnose cloudiness, show a real case, specify filter-media order or demonstrate a product outcome.

Original atlas illustrations

The betta portrait and conceptual shoal were created for this publication with OpenAI image generation in an engraved, hand-colored visual style. They are editorial illustrations, not photographs, species-identification records or evidence of a care outcome. The shoal is not a stocking recommendation.
