Animal-World Information about: Comet Goldfish

Comet Goldfish look just like regular goldfish but with a much longer and more deeply forked tail fin!

I had four pond goldfish for a while but lost three last winter. I bought three new ones. In the Spring and one lived only two days. Now the old one has developed a fungal infection on its tail fin. I put in bacterial and fungal treatment but let didn't help. I fished it out and removed the fungous manually but the whole tail fin came off leaving the bones. I flushed through the pond and added more treatment. Will this fish survive without a tail?

I have orange, red and pearly comets in one tank.My fishes do not seem to live that long. I battle to get the correct filters from my local petshop.

I am a pre-k teacher who is thinking about a classroom pet. I need something easy and fun. I was reading on a teacher blog about a pre-k teacher who got a comet fish. She seems to enjoy it. I am not sure if I should try a comet or a beta. Comet seems more entertaining but beta seems easier to care for. I think I have a small tank but I have no filter system and I would have to shell out the money. Beta all I need it a bowl it sounds like. Any comments appreciated. It is a big decision. Thanks.

    Get a betta they can live is small environments easily and are easy to look after!

    Bettas need at least 5 gallons with a heater and filter. Bettas live in rice paddies not puddles. lots of misinformation in the fish world.
    A Betta would be great, but the kids need to learn the proper environment!

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.

    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.

    It is not fair for the fish that you are giving it such a small tank. It will die quickly. Please get a bigger tank. Get another comet. The littler fish will bully it or vies verses.

I decided today that I wanted a fish! So my dad took me out and bought 2 comet goldfish and they are small so they are in a 5 gallon tank with a filter.  Water is cold and there are plants in the tank! They were fine when i brought them home but about 2-3 hours of being in the tank 1 started lying on the bottom of the tank and stayed there for a while. The other will swim aroud then lie at the bottom. They are still breathing but barely moving... Should i be worried? They will take turns lying down and i have been telling my little brother that they are 'sleeping' am i correct in saying this?

    It's a wonderful thing that you want to keep fish. I'm glad you're father helped you get one, and the goldfish are some of the easiest fish for beginners and great pets. Not sure what the problem is, it could be that they are adjusting... or there could be a problem with their water. The first thing I'd check is the temperature and make sure it's not too cold for them. Also, if you're using tap water, a water conditioner that removes chlorines and chloramines is necessary. Also make sure the filter is providing plenty of  water movement so the water stays well oxygenated. Good luck!

    Please increase the tank size as your fish can grow up to 1-2 feet and can leave up to 30 years. Gold fish bring a good luck if kept in right condition. Also, please take care of your fish, one day you will know how important to keep gold fish..

I went to go feed my comets/koi in my pond. I noticed my larger comet was being attacked by some smaller ones to the point there's a white spot on his side. Is it an infected fish? Or are the others just being bullies?

    It does sound like the large fish is being bullied, which of course causes stress and that can lead to illness.

    If you are not used to it, their mating behavior seems VERY aggressive. It is triggered by temperature changes. The males push the females against rocks often causing damage to their scales.

3 years oago we bought 4 small comets for our pond, approx 400 litres max depth 24' common depth 8-10'. The second year we had breeding, about 15 fry. the pond deicer failed and a few of the fry died. Come the spring we had 14 fish. Today I noticed one of our matures has an yellow bump on his head, centred exactly on the top of the head. Is this a feature or a disease ??

    A bump on his head could be several things ranging from a viral infection like lymphocystis or carp pox, a tumor, or more. Carp pox is rather common, it is viral but not lethal, and good water quality is the key to helping your fish with that or any viral infections.  Tumor are also occasionally seen too, and most commonly found on the head or body. A tumor doesn't look red nor bleed, and can be identified as a lumpy growth that is attached to the fish with a 'thread,', or several threads. They can grow quickly, and unfortunately are not treatable. Eventually a tumor will led to death.

I bought one gold and black, one orange and white platy 3 moths ago. Both are now all orange. I've been feeding tetra fin. Why would multi color disappear and can or will it come back? Mahalo

I have a Pond with Sarasa and Koi Goldfish for about a year. This is the first time I have seen Baby fish. I rarely see them come to top to eat and or swim, but I have seen at least three. I am concerned they won't make it and I am also concered that if there is more my pond will be too small for them. Can someone tell me more about what to expect during this time?

    I'm guessing the babies are the goldfish, because I have Koi and some juvenile goldfish in my pond too. The goldfish never come to the surface to feed, rather they wait for anything that sinks. I know Koi are more aggressive feeders, so that may be why.
