Look like yellow watchman gobies to me.

As far as a hobbyist is concerned, they are "yellow watchman gobies." There are actually several species that look pretty similar but they all should act the same in aquaria. The darker one in the back looks like it's a watchman (maybe a YWG but they usually don't get that dark) that is missing it's first dorsal fin. The lighter one up front could be a different species because of the blue patterning on it's face (more lines than dots).

I'd just call them "watchman gobies" instead of "yellow watchman gobies."

ok thanks, is there any way to check their gender?

Not really.
