Caution. Check the issues below before buying.

120L
Combined minimum footprint reference for these two species: about 120L (larger active fish often want more length).
Paradise fish (8cm adult) may treat small Chili Rasbora (~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.
