    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.

    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.

    YOU DIDN'T MENTION AN AIR STONE FOR OXYGEN? THE PLANT DOESN'T GIVE OFF THAT MUCH OXYGEN AND SOMETIMES CAN ACTUALLY CAUSE LESS OXYGEN TO BE PRESENT. SO YOU NEED TO HAVE AN AIR PUMP AND AND AIR STONE TO PUT PLENTY OF OXYGEN IN THE TANK.

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.

I have an adopted Comet fish. When found it was covered in Ich. I have been able to revive his condition thru water changes and medical treatment. However, the bright orange color of the fish has begun to change to white leaving only a tip or two of orange on the body. I just noticed a lump by his upper top fin that looks a blister. Does anyone have any comments about the color change and the blister?

    i do not know about the blister but the changing of colour can be because there is not enough light.

I recently bought 2 comet goldfish four days ago. While one is bright gold and very active, and eats eagerly, the other fish has gained black spots, it didn't seem to be eating well the first few days (today was the first day I saw it go to the top of the tank to eat). I read some of this being about the tank being dirty and to clean once a week, but I haven't even had a full week to clean it yet.
I did all that the PetSmart worker reccomended. He said a 10 gallon tank was the minimum for 2 fish, I have that, I bought the water conditioner and have a filter. I feed them twice a day. I am worried about the fish with black spots, and how to diagnose him and care for him. I am also concerned if this will be contagious to his tank-mate.
Any advice will help! Thanks!

    Scroll up in the article http://animal-world.com/encyclo/fresh/information/Diseases.htm fish diseases and symptoms and look at flukes. Also look at the other symptoms (in case) but flukes sound like what you are describing. The corresponding treatment is listed. Good luck.

    Hey,

    There are two reasons for this. First, the fish is stressed out in the new environment and that is why was sitting at the bottom. Second thing, the ammonia level in the aquarium must be very high leading to black spots on fish. It generally happens with the new aquariums when not properly cycled. Now since it has not been cycled, the easiest way to take care of it is to change the 30% of the water every other day. Remember when you change the water do not take out the water from the top..it won't help.. try to take out water from the gravel...it will take out the waste as well making the water more cleaner and healthier for fishes... u can easily get a vacuum cleaner from fish shop. Ok, one more thing, please dechlorinate the water before adding it to the aquarium. You can buy the de chlorinators from the aquarium shop.. Hope these suggestion helps you.

    We have one comet goldfish, eight years old now, extremely handsome and healthy. We change the water twice a year now. At first we changed the water whenever it wasn't "perfect" i.e. crystal clear. What has become apparent is that fin rot coincided with frequent water changes. Fish create their own enviroment and the water needs time to balance and settle down, often 7-10 days, fish don't mind a little bit of algae anyy way, they need their greens too. Always make sure the filter is clean and the air supply is freely flowing, do not put plants of any sort in the tank as they are the most common cause of disease, give each fish three match head size pellets per day, a feww grains of cooked rice or a few peas are good.

Hi all,
We just got our comet for my 3 year old. We have a 1.5 gallon tank. Our fish (Ponyo) is doing good he is small and I know he will grow and we will have to get a larger tank sooner than later. My question is; with comets being social could I add smaller fish such as neons or guppies or do I need to stick with another comet? Thanks for your help!

    Based on the size of the tank, I wouldn't add anything else. You would need at least a 5 gallon for 1 comet - and right now you have a 1.5. The things they do not tell you - not fair. I was never told about teenagers when I had children. Rule of thumb is 1 gallon for each inch your fish is going to be as an adult. Otherwise you have stunting and possible death. Comets grow to around 4 - 5 inches --- You have to subtract for gravel and plants.
    See fun - you get to justify a bigger tank. Rather than try to add guppies or tetras - even if you get a 10 gallon - I would stick with another comet. Just my thoughts. If I got one Great Dane - I had to have a second. If I got one Conure - I had to have a second. I just liked things sorta paired - my brain ...... Why not have a freind. You would need a 10 gallon for two comets.

  • zachary - 2011-10-10
    Yes you can add a neon or another small fish but it is a good idea to size up your tank before or as you get the fish. Neon's I would say are fine as long as they're not in high numbers and as long as your goldfish is none aggressive, if it's aggressive it will probably eat or kill the smaller fish and it may do so even if it is non aggressive. Gold fish are (in fact in most cases) herbivores but they for what ever reason will still eat a smaller fish not all the time but they do eat smaller fish.

Sarasa pond fish how long will she carry her eggs?

  • Charlie Roche - 2011-09-21
    Goldfish mature at about 3 to 4 years of age. Then as temperatures rise the female begins to produce eggs, and when the eggs are mature, the female emits hormones indicating she is ready to spawn. However, I'm not sure how long it takes for the eggs to develop into maturity.

    Once the female is ready, the male will push the female against planted matter, which stimulates her to drop the eggs. The eggs will attach to the plants and other surfaces. The male will fertilize them and then it takes about 4 days for them to hatch.

I have a mixture of comets (red/white) in my pond mixed with all types of goldfish and koi. They have all bred with each other and there are some neat colors. In the winter the pond freezes and the fish go to the bottom until the spring when it thaws out. These are great pond fish! Very easy to raise and get along well with others.The pond is about 3 ft. in the deepest spots.

    So, I plan to get two very small/young comet goldfish. I have a 80 litre tank ( which is huge to me), is that a big enough tank? I wanted to ask as I know that they grow large and that small space can stunt their growth.

    Btw, i might get one or more ancistrus fish to add to that later :)

      80 liters is about a 20 galllon tank. The comet goldfish will grow to about 4 inches each. 20 gallons and subtract room for gravel, plants and decorations and you have about a 17 gallon tank. Figure one gallon for each adult inch of fish and that is aproximate capacity. So your 80 liter is big enough for your two comets. Enjoy

      "4 inches"!? O.o
      I was hoping they would grow larger?

      Did you change anything? Like her surroundings or add more or less water, different tank?
    • stephen - 2010-03-17
      This isn't a good thing, try to find a website with good medical information, pictures to match etc. Goldfish are hardy but once they turn the corner it is an uphill battle to get them back. You can do it though, just make sure you take any carbon in your filter out while you medicate. Adjust water and filter flow so he doesn't get sucked up or damaged. You might even want to think about a hanging basket type thing so he can't hurt himself on the bottom. Above all check your water quality, although this sounds like a fungus to me water quality issues can do some really weird things. Good luck!

      I just had the same thing happen to my 3 of my pond comets that were between 7-9 yrs old, I have 4 fish in my outdoor pond had the water tested which was fine---they had some sort of cold water bacteria infection but by the time we figured out what it was and medicated the water they all died. I have one shubunkin left that's 11 yrs old and seems to be just fine.....good luck, Desa Fin is what we used if that helps.

      She'll be fine. It's problably that she's new to the tank, just like my comet goldfish, it acted like that. But sooner later it will eat n swim around.
    • Elaine - 2010-07-05
      Maybe a case of black ich.
    • Chris - 2010-07-07
      That's what my fish had too! Only the spots were red, he was about 8 years old and yes he did die this morning, what could help your fish is an AquaSafe Water Conditioner for Gold fish. It helps any type of gold fish. if your fish also starts to lose it's scales that means it's dieing too.=(
    • ally - 2010-10-11
      I hate to tell you but I think your fish is dead.
    • Lisa - 2010-11-14
      My fish is doing exactly the same thing.
    • shaunna - 2010-11-16
      You should get a new one or try to not give her food then she'll feel bad and will get hungry then you can feed her.
    • Kshal - 2010-11-21
      Being an amateur in breeding Comets......I wish to tell you that maybe your comet is hurt by any part or object from your aquarium... or it may even be infection from other fish in your tank.... You can use fish medicines......or try to isolate your fish.
    • Gina - 2010-11-21
      What size of tank is she in? Do you do weekly water changes? Doing 30% water changes weekly might turn her around. The black spots might be burns or infection from bad water quality. If you think it's the water. Change 50% and use a fresh filter.
    • benoo - 2010-11-30
      Hi you should check either the wiki or your local non petco/pet smart pet store if not do a google search.
    • jason - 2010-12-11
      It depends maybe you have it alone...usually comets can't be alone for too long or they will die...as a reminder comets can't be over crowded either because they can easily get emonia and slowly die.
    • jason - 2010-12-11
      Or maybe it all ready has emonia. My comet had purple spots so i took it to my job and it had a emonia. . . Trust me i am a manager in a vet center i know what i'm saying.
    • Denise - 2011-01-20
      I hope your comet goldfish is doing well. I do know that if black spots appear on the fish you may need to change the water more often. The fishes urine may burn their scales. My comet had the same thing. I change the water now once a week and change the filter. They do better with a filter in the tank. I hope I'm not too late!
    • elizabeth - 2011-04-15
      What I think - They are cool fish.
    • Lily Mae Flynn - 2011-07-15
      Get some quick medical attention to that fish I had a fish once and it died from doing exactly what your fish is doing.
