What do you know about fish??????

[Little Lee]

I have a gold fish and when i got him he was so perfectly orang and i clean his little tank once a week (every saturday) but for some reason he has been getting black spots on him i only have had him for 3 weeks. Why is this happenening and what can i do about it?

The fish's color is just changing a bit, kinda like how a baby's hair is usually blonde and when they get older it gets darker. There is nothing to worry about!

It could be evidence of ammonia burns, or a natural color change.

What size tank?
Do you have a filter?
Have you tested your water?
What type of goldfish?

A goldfish tank should never be "little". A single goldfish should have at least a 20 gallon aquarium.
