Surprise of colorful fish [from contaminated water]

Good day my friends
It was amazing what happened to me today, and it was an idea that I had for days, and I will comment ... And it is that near my house there is a lake (to my estimation it was contaminated water) that is about to end; so I took the task of removing some fish that lived there to repornelo to another site with more vital liquid, and can carry out this task; but my biggest impression was the colorful fish, here you can see some ...

Tomorrow I will have to take them to a better place ... Bless !!!

Postdate: I do not know about fish, but could anyone tell me what species they are?
