Animal-World Information about: Comet Goldfish

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

What is considered as aggressive behavior for comet fish, and what signs do you look for when the comet fish is not doing well? My husband and I just bought 4 comet goldfish and 3 of the 4 are doing great. One looks stressed and anti-social, and not really eating. There is another one though that isn't hurting the other fish from what I can tell, but it kind of nips behind one of the other ones, I don't know if this is a male trying to mate with a female or if it is being aggressive, please let me know. I know they are all still getting used to their new environment, but I want to be sure to do this right as I am an amateur at this. Any advice would be greatly appreciated! Thanks!

    I know this sounds rude... but i have a felling that you probably have a tank too small.

    Anyways, I'm not sure what to do, but you may have to isolate the fish somehow.

    goood luck :)

    Yeah sometimes you canjust get a goldfish and he is in the time where all he does is empty. Goldfish produce a lot of waste - it is normal. They don't really have a stomach so what goes in - comes out. Feed him a little a few times a day - not a lot once a day - that might help.

I just bought 3 either sarasa comet goldfish or comet goldfish (can't tell difference) about 5 days ago and it doesn't eat the food I gave them. My tank is extremely clean and is 100 gallons. Their tankmates are all goldfish. 10 tankmates and the biggest tankmate is 2.5 inches. My 3 sarasa/comet is about 3.25 inches long. I feed them floating pellets for goldfish and tropical fish. And it said on the brand, only for ornmental fish anyways the won't eat. But if they do they spit it out. They are small pellets. Somebody plz help!!! And btw I learn that fish don't eat in their new aquarium for a few days but it been almost a week! What can I do?

I just bought my two first comet fish do they have to have a pump? The pet store said they don't?

    Yeah they need a pump. They told me I didn't either and 2 of them ended up dying within a couple days . It would be best cuz they use a lot of oxygen and poop a lot!

Just got back from a business trip. My comet tail is upside-down, has very shallow rapid breathing and has what appear to be white-ish "veils" on her belly and, possibly, in her gill slits. What can I do quickly? She's about 7 years old and is about 9 inches in length.

    Make sure there is enough aeration in the aquarim, check the temperature (too hot?), check for ammonia or nitrite and do a large water change (say 50%) if they are detected, and put in a dose of ich medication like aquarisol, rid-ich, etc.

HELP! again...

I just got back from spring break and I put him back in his 10 gallon tank with distilled water (my college has really bad water problems. Students aren't even allowed to drink or do anything with the water without boiling it. I've had fish die because of the water, even when treated). I put some stress coat and aquasafe in the tank. Then once I turned on the filter it started smelling like sulfur. I took my fish out again and have him in his traveling container, but I don't know what to do about the filter and stuff. I read some things about water smelling like sulfur. All I really got out of it is that something is wrong with the filter, some peoples fish died, and the water got cloudy (which I took my fish out before anything could happen). How do I fix the smell and will the water be safe for my fish if I just take my filter out? He's not exactly happy about being the traveling tank, so a fast reply would be greatly appreciated.

    I'm going to redo the tank with brand new water again. I'd still like to know if it's safe to use my filter or if it's the chemicals. I never had this problem before when it came to this.
  • Justin Brough - 2011-03-22
    Here's the fast reply - NOT (sorry). What kind of filter is it? Can you just change the material in the filter and any carbon or other resins in it? The problem with starting over is the biological filter will be wiped out. Best to keep at least the gravel and/or whatever ornaments you may have.

3--18--2011-----I have had comets for about 4 or 5 years--"the Raccoons like them for lunch--

I have outside pond in Northwest Wa., and the comets have come through the ice and snow real well, they do well with the rain water, seem to be very hardy--I have about a 40 gal pond with a waterfalls-they are nice pets--really enjoy them--

I got my fish yesterday but it just swims into the wall of the bowl. Is it just lonely because I only got one?

    All goldfish are social fish and do best in numbers.

    You shouldn't ever put a fish in a bowl, and you should keep at least two.

    It's about the same.

I bought a comet goldfish and I really like it and I think that the comet goldfish is easy to take care of. The comet goldfish are very pretty to keep for a pet, so if anyone who ever wants a fish for a pet I would recommend them to get a comet goldfish.

    Not so they get bigger it will be harder to care for..after let's say 3 or 5 years try getting a 30 gallon aquarium.
  • Isabel cormier - 2011-02-28
    I agree. I have two comet feeder fish (goldfish) and they are doing great. I say that they are for ages 8+ so that they are feed properly and looked after. For those wondering they must be feed two times a day. If you have small flake food feed them as much as they will eat in two min.
