*This is not a pipefish. Just a funny picture of a fish. Do not be deceived*
The Microphis deocata which is a type of pipefish is a special case when it comes to their dimorphism between sexes. In this case, the females have the colorful and dramatic features while the males have the more plain and basic characteristics. In most other species, the opposite is true and the males are more extravagant than the females. Pipefish are unique in this way because the females are actually courting the males rather than the usual other way.
Since this is against the norm, one may question how this could be possible? I believe this occurs due to the male's ability to get pregnant. Considering that males are the ones getting pregnant, they are the one who have a longer time to invest and contribute to the reproduction process compared to the female. Therefore, the males can be picky on who they mate with because they need to know what they are investing into. In response to this, the females have developed pronounced characteristics in shape and color to attract males for mating. The main driver of this sex role reversal is the male's limitation of investment. Overall, the Microphis deocata are a fascinating species that have developed characteristics which are usually contrary to the rest of nature's approach to sexual dimorphism.
I agree with all of your comments on why the females are the ones doing the courting in pipefish populations! It's interesting to think about it from a different point of view that it's not sex that matters, it's who invests more time in the offspring. I also enjoyed your attached picture of not a pipefish, but a fish that looks very polite.
