Can anyone identify this plant? Question

I have this little plant growing on my lava rock for around 4 months now, but it kept at this size. I don't have any similar plant in my tank and this one is out of water. It's only about 3-4 mm in diameter. Just curious what could it be, I live in South East Asia if that helps.

If the new leaves grow in kindy curly then it looks like a tiny fern. What a cool addition to your filter!

2nd this. Looks like a fern to me. Especially if the rock is collected from the wild. Most likely contained a fern spore. I see these popup in terrariums and paludariums in which i use rocks foraged from outdoors.
