Help with your choice

Dwarf Neon and larger rainbows need different plans

Praecox, Maccullochi, Boesemani, Lake Kutubu, Banded and other named rainbows remain distinct choices. Compare adult size, swimming room, water and social needs for the exact fish rather than applying one dwarf-rainbow recipe to the entire genus. Keep locality or form information with the fish if it is supplied.

Compare the stated fish and quantity

The range includes individual offers, two explicitly six-fish packs and an assorted selection. Read the stated quantity and grade when comparing prices. An assortment does not guarantee a named locality, sex balance or matched breeding group, and a juvenile photograph does not establish the colour of every adult supplied.
