Mystery grunt in Tropical Eastern Pacific (Mar de Cortés)

[itziar]

Can anybody identify the grunts in the background of this photograph? Shapewise they looked like Burrito Grunts (Anisotremus interruptus) but I cannot find any photos in the web with the horizontal stripes these specimens displayed.

White Margates in the Tropical Western Atlantic also display occasionally these kinds of stripes, but they are not present in all individuals. I wonder whether the same happens with Burrito Grunts (or any other grunts) in the Tropical Eastern Pacific... I am looking at the REEF Fish ID book Baja to Panama by Humann and DeLoach and I cannot find any other correspondance.

Any ideas?

In a different forum, it is suggested that the juvenile patterns of Burrito Grunts might be showing in a full-size version of them: TEP grunt in Gulf of California | Reef Environmental Education Foundation (REEF)
