What are these fish?

[Chickenboi]

So I went to a local fish store and they had these fish. I asked what they are and the guy said that he didn’t know what the first fish are. I asked him about the second fish and he said it was a killifish but he didn’t know the species. And sorry for the garbage pictures of the killifish. Thanks in advance!

They look like least killifish, Heterandria formosa.

I should of mentioned this but the fish in the first pics is around 3 inches long.

Well, probably not H. formosa then. Unless they've been hitting the steroids. Sure look like them, though.

I bet it's something in that genus, though.

I put the 2nd image into Google lens and it said that they were Empire Gudgeons. And the fish in the 5th and 6th picture look like they are female golden wonder killifish.
Edit1: I added the 2nd sentence
Edit 2 I put the 5th picture into Google Lens as well and it said that they were mosquito fish

Yeah the pics are very bad. If I go again soon I will get better pics
(edit I I searched up Empire Gudgeon and it looks like it is one. So case closed for the first fish.)

Two dorsals says a gudgeon.

I think the second fish, because the dorsal is so far back, might be Aplocheilus blockii. It's a blurry shot though.

 

[emeraldking]

It looks like a female empire gudgeon or a juvenile male empire gudgeon. Young males look like a female before their definite colors will show up. The second fish is a bit hard to determine by these blurry pics.

 

[Chickenboi]

I looked up empire gudgeons and it looks like that is what it is.

Nnnnnnnooooooooooo

The bigger US mosquito fish perhaps? I can’t remember the name.
