When i started the hobby a few years back, i bought some rasbora maculata, but i didnt know much about fish at all. There where some sort of different fish in there, now i know a bit more about the hobby and i recently caught these fish and put em in a seperate tank.. They are witouth doubt the smallest mature fish i have ever owned. They barely are half the size of a mature red cherry shrimp or 1cm.

Least killifish?

No, dont think so, mine are smaller than those fish, also mine have a little black dot on the start of their tail. Their bodyshape seems to be more streamlined aswel

Boraras urophthalmoides?

I'll go in a similar direction as Mr. Limpet. How about Boraras Micros. 1.3 cm long.

Boraras urophthalmoides has a maximum size of 4cm, although it really looks a lot like my fish, they are definately a lot smaller. Boraras Micros size seems about right, but the pattern seems different, they seem to have dots on the internet, my fish definately have a black line.

I think its Boraras urophthalmoides after all, except for maximum size i cant find any differences. Those fish are pretty rare here xD. I've never seen them sold again after that one time, and i have browsed aquarium shops all over the country

I'd agree with Boraras urophthalmoides. The latest issue of Practical Fishkeeping (Spring, 2016) has an article on Boraras sp. and lists max size as 1.6 cm which makes more sense. Check out this as well:
