One of my orange tail guppies is starting to turn into a black-ish color in the tail and on its scales... its a little smaller than the yellow tailed guppie. I just wanted to know what that means. Or if its ok.
And one of my mollies likes to stay towards the top of the tank (still moving) like with its nose touching the top. Is that alright?
