Whats The Name Of This Fish?

So for a few weeks now, ive had this fish and I have no idea of what it actually is. When i bought my weather loach the staff told me that when getting the dojo loach (weather loach) this fish jumped in and she left it. So now im not sure what species it is. Its always swimming with my weather loach and they seem pretty close lol. Hes fast and seems to be nocturnal as he hides all day and comes out at night. Any ideas?

got a picture that isn't blurry?

I'll try but this little fella is very fast and its hard to take a picture of it as it hides most of the time
