Compatibility brief
Can Green Terror live with Lemon Tetra?
Risky. This mix is commonly discouraged for typical setups.
Green Terror + Lemon Tetra: Aggression mismatch. Green Terror is aggressive, while Lemon Tetra is peaceful. The aggressive fish will likely bully or harm the peaceful one. 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).
Green Terror (30cm adult) may treat small Lemon Tetra (~4cm) as food once grown — plan adult sizes, not shop sizes.
Green Terror (aggressive) and Lemon Tetra (peaceful) are far apart on aggression — bullying or injury is a common outcome in average community layouts.
