Please identify! Killifish?

So this mystery fish appeared in an uninhabited planted tank a few weeks ago, and I though it was just a figment of my imagination, since nothing has been in here since some bolivian rams spawned almost 6 months ago. Just plants! All I've added to the tank since then, is moss from a shrimp tank, some blyxa japonica that was dipped in PP and H2O2, and some assassin snail babies.

So I'm thinking it must be a killie of some sort, or maybe something else. It looks a bit like my golden wonder killies, but they've never touched that tank (nor have I used a net between the two tanks.

So I went to take pictures of this mystery fish, and i moved a piece of java moss, and 5 of them shot out, they are VERY shy, and do not like their picture taken. Right now they are about 1-1.5cm, and they haven't grown much in the past few weeks.

Here is a picture of one that I got to stand still for half a second while I snapped one off:

Kelso's Avatar's very hard to tell, the fish being so small and translucent, however, the general body shape is that of a killifish. If I recall correctly, they spawn in plants.

1 Otos, 6 Guyana Leaf Fish, 2 Malayan Leaf Fish, 1 Orange Head Tapajos, 4 Bronze Cories, 3 Peppered Cories, 2 Panda Cories, 1 Skunk Cory

3 Thread-finned Acara, 1 Jurupari, 1 Spiny Eel, 1 Bristlenose Pleco, 1 Festivum, 1 Spotted Raphael

Well, yes, some spawn in plants, and some in dirt. And the body shape/mouth look like killifish, but I'm really trippin out here. I have absolutely no idea how they could have gotten into my tank, unless they were transferred quite a while ago (6 months or more) and then waited to hatch until recently. And as far as I know, the plant spawners don't work like that, but the substrate spawners need a dry time, so I am so flummoxed.

I readily admit to very limited knowledge of killifish; I had a few species some 30 years ago, and at that time knew someone who specialized in them. Most of that has been forgotten, but I think that eggs laid in plants can survive months if kept moist, and that is how they are frequently stored and shipped.

Here is a killifish site with probably hundreds of photos (click on "pics" in the upper left) and info. With your fish at hand, you might be able to find them pictured here:

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]
