Height, growth, and predation realism
Freshwater angels are laterally compressed cichlids that need tall aquascapes plus calm corners. Nano fish that fit in adult mouths disappear eventually even in “peaceful community” tanks - respect adult size rather than juvenile innocence.
Water chemistry discipline
They tolerate moderate hardness but sudden osmotic whiplash stresses slime coats. Blend change water gradually when switching sources and keep dissolved organics modest; heavy protein skimming substitutes do not exist in freshwater, so water changes remain the blunt instrument that works.
