Compatibility brief
Can Banded leporinus live with Guppy?
Caution. Check the issues below before buying.
Banded leporinus + Guppy: Temperament difference. Banded leporinus is semi-aggressive, while Guppy 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.
300L
Combined minimum footprint reference for these two species: about 300L (larger active fish often want more length).
Banded leporinus (25cm adult) may treat small Guppy (~5cm) as food once grown — plan adult sizes, not shop sizes.
Banded leporinus is a fin nipper and Guppy is vulnerable to nipping — long fins are a common target even when water parameters match.
