150L
Combined minimum footprint reference for these two species: about 150L (larger active fish often want more length).
Electric Blue Acara (18cm adult) may treat small Guppy (~5cm) 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.
