Nope it's not

It's not a Goby, Gudgeon or Prehistoric(obviously) fish

 
Here's another clue. You got a little bit closer there with the latin name NY

Nope
 
The Latin was getting closer with the Perccottus glenii though

Amur sleeper? Perccottus glehni?

 

[Ny82]

I know you've already said it's not a goby or gudgeon but I keep coming back to chinese sleeper!

Yup, way off... Never owned a Channa

 
Would this help more? I know my pictures are pretty bad because of them being from my old phone so I searched and found this one for you to guess from

This is a google image, not mine.

 
Not a Goby/Sleeper or Gudgeon. 
 
They do vary in colour from male to female(only during breeding season though) and between moods

 

[Ny82]

Still looks like a sleeper to me lol 
 
rhinogobius nantaiensis? Is that us back to the same thing again lol

Slimy sculpin - cottus cognatus?

Slimy sculpin - cottus cognatus?

 
Well since you have the right family both of you it's Cottus gobio - The European Bullhead I had 5 of them. 3 females and two males. Originally started with 6 but one of the males took a dislike to the small female and ate her
