Unexpected A. paulmuelleri behavior.

[Hellfishguy]

While a young pair of A. paulmuelleri are looking after their fry in a community tank, the male has taken on the brood care coloration of a female, & the pair's mother, more colorful than I've ever seen her, is patrolling the periphery of the couple's territory. Has this been observed in any other species? Photo is of the fry's grandmotherView attachment 8086

This isn't common but not really rare, especially in community situations.
