After some reading and watching my own pair of cleaners, I’ve spotted some common differences between the genders.
So, it seems that Lysmata amboinensis is a protandric simultaneous hermaphrodite. Protandrous simultaneous hermaphroditism is the “early male reproduction and later reproduction in both sexes”.
Now, I have what I assume are a bonded pair of Lysmata amboinensis.

The larger of the two is what I assume to be a female. These show some brighter colours, with the yellow body being VERY dominant. They also seem to reach some large sizes with their antennae hitting about 4-5 inch long, their main body hits 3 inch.

Whereas the males seem to have a much less defined body with the colour being a pale yellow. They seem to get about 2.5 inch max with their main body length and their antennae seem to get to 3-4 inch long.

Here’s a photo of each of mine this morning (Lights aren’t on yet)

Ok, super confused. Is there sexual dimorphism or not?

They have fully functional male and female genitalia when mature, while I don't believe they can self fertilize, any two can be a pair and both can carry eggs at the same time.

If I remember right, they start as male and when they're big enough to carry eggs, they also become female. That means sexual dimorphism sort of need not apply, as they are always both as mature adults.

Thank you for this. Even though it still leaves me confused
