While eating rainbow fish heals 11 hitpoints, they are nowhere near as popular as other fish that heal a similar amount, such as lobsters, because players must use stripy feathers as bait rather than regular feathers. It is also possible to loot them from gourmet implings, or as a drop from sulphur lizards.

Despite being called rainbow fish, they only have four colors (yellow, light blue/turquoise, dark blue, and grey).
