Caution. Check the issues below before buying.
Corydoras Catfish + Opaline gourami: Temperament difference. Opaline gourami is semi-aggressive, while Corydoras Catfish 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).
Opaline gourami (15cm adult) may treat small Corydoras Catfish (~6cm) 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.
