I take it back, zoomed in and the first fish is a male, you can see the tube, the second is a female. Had thought the dorsal on the fish on the right seemed taller and slimmer.
You have a pair.
Thanks!! Are you describing the spots I highlighted in these? Arrow being male and circle the female?

Yes. The area is often easier to see in fish in water viewed from the side or when acting normally (as they have s tendency to rest slightly on their sides). The tube becomes more clearly visible in the males.
Another point to note is that it is thought the males impregnate the females a little like livebarers. (I did not witness this action in my group but kept finding eggs in jelly.)
Then the female lays eggs in jelly. However, once impregnated the female does not have to lay eggs. It has been proven that she can store sperm. And there have been cases where a single female has laid fertilized eggs weeks/months after being removed from a group.

Moved the O. eigenmanni into the 120g now that they have healthy looking bellies. One dove into a bamboo cave with one of the striped Raphaels so we will see how communal they are.PXL_20220128_041037581~2.jpg
