Compatibility brief
Can Congo Tetra live with Senegal bichir?
Risky. This mix is commonly discouraged for typical setups.
Congo Tetra + Senegal bichir: Senegal bichir may eat Congo Tetra. Senegal bichir (35cm) is predatory and Congo Tetra (8cm) is small enough to be eaten. This pairing is unsafe. Real tanks add variables Fishori cannot model; treat this as a high-risk read, not certainty.
Compatibility score
Profile confidence: medium
Order of checkstank volume vs adults → predation mouth gap → temperament / fin nipping → shared water windows.
300L
Combined minimum footprint reference for these two species: about 300L (larger active fish often want more length).
Senegal bichir (35cm adult) may treat small Congo Tetra (~8cm) as food once grown — plan adult sizes, not shop sizes.
Temperament gap (peaceful vs semi-aggressive) — can work with space, structure, and careful observation, but not a “drop and forget” mix.
Assessment details
Temperament difference
Senegal bichir is semi-aggressive, while Congo Tetra is peaceful. This can work with adequate space and hiding spots, but monitor for bullying.

Next steps
Concrete changes, not "research more" filler.
- •Provide plenty of hiding spots and visual breaks so Congo Tetra can escape if harassed.
- •Congo Tetra should be kept in a group of at least 8 for best health and behaviour.

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

Plan further
Try both species in the full-stock tank check, or open either fish profile for mates lists. Methodology explains how verdicts are produced.
Individual fish vary in personality. Fishori uses conservative hobby rules. Observe any new introduction closely, feed thoughtfully, and keep a quarantine or backup plan. This is not veterinary advice.
Profile data confidence: high. Based on multiple reputable aquarium care sources with strong agreement.
