Ember Tetra + Golden Wonder Killifish: Golden Wonder Killifish may eat Ember Tetra. Golden Wonder Killifish (10cm) is predatory and Ember Tetra (2cm) 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: low
Order of checkstank volume vs adults → predation mouth gap → temperament / fin nipping → shared water windows.
80L
Combined minimum footprint reference for these two species: about 80L (larger active fish often want more length).
Golden Wonder Killifish (10cm adult) may treat small Ember Tetra (~2cm) 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.
