Goniobranchus fidelis has a creamy white mantle with a broad orange band around the mantle edge and a thin wine red line between the white and the orange. On the inner edge of the orange band there are usually a series of tongue-like patches running into the white region. In some cases they are almost all wine red while in others there is only a slight thickening of the red band. The rhinophores and gills are black, the foot is white. It grows to 20-25 mm long.
