Primary: aquarium size, water chemistry, behaviour, and compatibility (URL verified in upgrade script; recheck if site content changes).

Secondary: taxonomy, distribution, and maximum length in nature; cross-check with aquarium import lines and measured tank parameters.

Secondary: general species context; verify all husbandry numbers against a dedicated aquarium care sheet and your test kit, not a single table row.
- Seriously Fish. Polypterus senegalus (subspecies: senegalus)
Primary: aquarium size, water chemistry, behaviour, and compatibility for the Cuvier bichir complex; Seriously Fish slugs the subspecific form. Use as the vetted care profile even when retailers only print Polypterus senegalus.

Secondary: range-wide data and size for the complex; reconcile with the exact import's locality when biologists care more than a shop price tag does.
