Went down to my local city dam for a quick fish.
Managed to catch my first vlei kurper for the season.

And then hooked into a 23mm male mosquitofish, beating my previous smallest by 5mm!

The male fish are significantly smaller than the females and have an elongated anal fin (gonopodium) used during mating.
I usually only catch the bigger, fatter females, so this was a
treat.
Used a tanago hook and extremely small fleck of white rubber lure.
Cheers
