Compatibility brief
Can Angelfish live with Lemon Tetra?
Caution. Check the issues below before buying.
Angelfish + Lemon Tetra: Temperament difference. Angelfish is semi-aggressive, while Lemon Tetra is peaceful. This can work with adequate space and hiding spots, but monitor for bullying. Outcomes still depend on your tank shape, maintenance routine, and individual fish.
Compatibility score
Profile confidence: medium
Order of checkstank volume vs adults → predation mouth gap → temperament / fin nipping → shared water windows.
150L
Combined minimum footprint reference for these two species: about 150L (larger active fish often want more length).
Angelfish (20cm adult) may treat small Lemon Tetra (~4cm) as food once grown — plan adult sizes, not shop sizes.
Temperament gap (semi-aggressive vs peaceful) — can work with space, structure, and careful observation, but not a “drop and forget” mix.
