    Perfectly normal.

    If your fish continues to turn black, as if it is spreading, that's not normal. I bought feeder goldfish from Petco once and I picked one out because of its pretty black tail fin and gold body. Later that week I noticed black on all of his fins, around his eyes and still spreading. I called Petco and explained and the guy told me that sometimes fish catch this disease nicknamed the 'fish plague'. He said there is no known treatments and that experts aren't even positive whether its a parasite, bacteria, fungus, ect. He said basically that my fish is going to continue to turn black until he is completely black and then he'll die. I was like 'Thanks' sarcastically of course. Why are they knowingly selling sick fish? Anyway, eventually I started to notice black spots on the fins of my other previously healthy fish, so just keep this in mind.

I've had my 5 comet gold fish for over 9 years, in a 40 gallon tank. I have one 9 year-old Cory Cat in there as well. I recently bought them a different type of fish-food (TetraFin - Goldfish flakes), and they literally started dying one by one. I started treating them with the 'Melafix' medicine I bought from my local department store, it hasn't done anything. Also, my tank is very old, about 12 years-old. But, I haven't the money to get a new one.

They've lived peacefully and happily for years. I don't know why they are all dying. I've had them since I was a child, and seeing them all go like this makes me sad.

    Why did you treat with the Melafix? Could just be dying of old age if they are all around the same age.
  • Gabriella - 2012-05-07
    I thought that they maybe had some-sort of common goldfish disease. Several people told me to treat them with Melafix to see what happens.

    As they age they do change colors and can get different patterns.

    As fun as it may be. It is always best to not have your hands in the tank unless they are completely clean. Soap and perfume can be harmful to the fish.

Can I put black moor in with a comet goldfish? Will they fight? Think I put one in there with her but not long

    Yes, Black Moors, and Comet Goldfish can get along. They will not fight. Goldfish generally can be placed with almost any other Goldfish.
  • Jeremy Roche - 2012-03-10
    They will get along. Make sure the take and filter is large enough for these fish. They create a lot of waste.

Can someone please tell me how heavy 2 inch goldfish are?

  • zach - 2011-10-10
    that is a hard question to answer because the weight of the fish does not have to do a lot with the size so much as the fish's eating habits. i have had many fish 2,3 inch's long and not one was the same weight.i would put a bowl of water on the scale and put the fish in and subtract the weight of bowl and water from the fish.
    hope this helps.

    I saw something to not put a plant it gives them a kind of sickness. I am so sorry in my town 600 of mine died. I loved them but the birds had a party.

    Give it time as he might been spawning. I got mine from the fair he did that to. I called pet store ask them about that --- they said was normel.
  • Alex Burleson - 2012-02-08
    A Comet Goldfish will require a minimum of 10 gallons, if not 20 when fully grown.

    To ensure proper advice, I would need more details on your aquarium, such as the size, temperature, and how long it has been running.

    Feel free to email me, if you wish:

I fave a few gild fish and they are growing big the problem is they have red coloring on there body what does it mean

My daughter as 3 small comet fish. None are larger than 2 inches. They are in a secure tank void of any spaces for them to jump out. My littlest one is missing. No one was near he tank and I can't find it in the tank anywhere. I was so freaked out, I even looked in the filter. I don't have any explanation for the missing fish. Has anyone ever had a situation similar?

    Mystery solved. The little one must have been hiding in a crevice of the ornamental piece located inside of the tank. After I submitted my comment, I went to the tank where little one was briskly swimming along with the other two. I guess I panicked but I seriously looked for it for over an hour.
