Compatibility brief
Can Guppy live with Rainbow cichlid?
Often a workable match in a suitable, well-run tank. Still verify behaviour in your setup.
In many setups, Guppy and Rainbow cichlid are often kept together in a suitable peaceful community when temperature and pH are matched and the tank is sized for adults. Individual behaviour, filtration, and layout still decide whether it works in your home.
Compatibility score
Profile confidence: high
Order of checkstank volume vs adults → predation mouth gap → temperament / fin nipping → shared water windows.
200L
Combined minimum footprint reference for these two species: about 200L (larger active fish often want more length).
Rainbow cichlid (12cm adult) may treat small Guppy (~5cm) as food once grown — plan adult sizes, not shop sizes.
