New goldfish with black lines?

Question

Okey, this little fella is supposed to be orange but he has black stripes on his side and top fins and also one line of black on his tale, what is this? I have him 2 days now and I saw it first yesterday, and first he was very active, now he likes to be at the bottom, he´s not eating much either but sometimes swims to the top and sucks the air. He has plenty of water which I have changed twice with filtered water, he has stones at the bottom, a mirror and light on a good few hours a day.

What´s wrong with him?? I read to bath him in salt water, is this right?? Has he a disease?

Answer 1

thats ok its natural for them to change black don't worry

Answer 2

You had him for 2 days? And you've already changed the water twice? Whyyy? You shouldnt do that. you should do water changes once a week. Twice in 2 days is way too much for him.

Is he in a bowl? or a proper tank?

Your fish is just adjusting. Its very stressful being moved into a new home.. And even more stressful when you keep changing the water. Let him be for a few days, and see how he goes..

Dont give him a salt bath. You just bought him two days ago, if you stress him too much he could get really sick and die.
