Meratus priapium fish (Phenacostethus sikat)

This thing is very hard to see. They're very tiny and I couldn't find it in its exhibit.

@Fargusno they moved a lot around, so they technically don't hide a lot, you just have to extra focus and have the patience to look at one or two little movements around.

Anyway, this species was only found and described in 2023, and they're currently known in river systems around the Meratus Mountains range in southern Borneo.

The male of the species are unique that is their genitalia is located below their head.
