I had 9 comets which were all about 15 cm long in my pond until the other day when two kookaburras decided to eat 6 of them. It was then that I noticed that I had about 25 baby comets swimming around at about 1 to 2 centimeters in size. Life goes on.. Take that kookaburra!

Last night my comet jumped out of the tank. I woke up this morning to my roommate screaming and crying because she almost stepped on him. When I went to see him, I noticed he was laying on a pair of pants. I moved the pants and his tail was stuck in the position it was in. He appeared dead and completely dried out. Then I noticed his tail started to move a little bit. I quickly snatched him and put him back in the water. I was completely shocked when he started swimming again. This fish was our baby, I love him. Although he appears to be hurt. He's swimming normally, but occasionally spazzes out. He must have had a hard impact. The fish tank is located on a 4ft tall dresser, and we have a tile floor. He's missing a line of scales on his one side and when we found him he was completely dried up. Is there anything we could do to make sure he's okay? We can't lose him.

    I think he was only spazzing because he went under the filter waterfall and it probably hurt him. He seems to be doing okay. He is swimming normally but seems to be tilted slightly. He just appears to be tired and sad. He's mainly sticking to one area of the tank and seems to be enjoying the light when it's turned on. He swims occasionally but just relaxes mostly. I can't even imagine what it would be like to fall off a 4ft dresser and other things, go without oxygen for that long, and survive. He's definitively a trooper. Especially when we've only had for a few weeks.

    What are the signs of infection?
  • Taylor Sharp - 2011-02-23
    He's acting pretty normal now. He ate some, he's playful, and back to being the amazing fish he was last night. The only thing that concerns me is that he is still tilted. The weird part is he only does it when we shut the light off above his aquarium. Other than that, he swims normal when the light is on? I've never seen anything like it.

    For the night I decided to take two gallons of water out of his tank. I highly doubt that he will try jumping again considering he is hurt, but my room mate wouldn't sleep if I didn't take the water out. I'll keep you posted.

    I have a problem. His tail has this see-through color and it's starting to deteriorate. Should I get him stuff for finrot?

I have just bought my first goldfish, 4 comets and 1 shubunkin, and put them in a 500 gallon outdoor pond and they are doing great! I was wondering if and what types of fancy goldfish I can put in with them. My petstore sells an assortment of fancies with XL. I live in north central Florida and it only gets to about 20 degrees. It would be great if I could get a reply.

    Fancy goldfish tend to not do well with comets and shubunkin, due to the fact that they are weaker swimmers and cannot get to food as quickly. You can solve that by sprinking that food in multiple areas, and watching to make sure the fancies get enough to eat. Any type of fancy goldfish will be able to live with comets, since they both thrive in similar conditions.

    Comets are more hardy and can live in a Pond outside. Fancy goldfish have special needs and won't do well in the winter, they are not as hardly. It is best to keep to the comets and shubunkins. Since your pond is small don't overcrowd them either. They will grow a lot larger up to 10 inches or more and need space. Your pond might even attract some frogs and dragonflies too.

    I have an outside pond that is 585 gallons. Along with the 3 Comets I was given my first year (3 yrs ago), I bought 2 Ryukin. I was told they may not make it through the winter (I live in southern NJ). One died 2 months after I got it. The other is still alive & well! I also know people that have Fan Tails in their ponds that are doing well year after year. Not sure about other types. I know a guy in my area that runs his own fishery. He has several types of fish that he breeds & sells that spend the winter in a pond on his property. Doesn't seem to have a problem.

    It is impossible to place a fancy goldfish with a comet because it can cause emonia and they will end up fighting.
  • Dalten - 2011-01-07
    I have a comet and a fantail they seem to enjoy each other I think that fantails are very fancy. Fantails can get to 8 or even 10 inches when keep in proper conditions.

I had gotten 7 comet fish out of a friends pond, over the past 5 years all but one has died, one passed yesterday. The one that is left is awfully sad. =( I'm able to get one or maybe two more comets! But where I live the only pet places are Petco.... and at petco most of the time there are only baby comets because there used as feeder fish. And I would like you fish experts out there to tell me if my 3 inch male comet would EAT, the little baby comets....... Please help! Need an answer ASAP! Thanks!=)

    Hey I think you should just buy another fish bowl and wait to the babies grow up. And btw I think the male wouldn't eat em but don't know 4 sure.
  • Editor's Note - 2010-08-27
    Big fish may eat smaller fish as a rule.
  • Chris - 2010-08-27
    Thanks, I have gotten another one, but, this little one was alive for a month but just passed from an unknown illness. She had a small black spot UNDER her scales. It was on her left side near the top. This has happened twice before. Do any of you know what it is?
  • Lauren - 2010-09-04
    No, they are not cannibals. I have little tiny comets with my giant comets. They all get along just fine
  • Jonny - 2010-09-13
    As long as the baby fish have developed fins and a tail they should be fine. I've recently introduced half a dozen 1 inch shubukins to my pond and they're getting on fine with the bigger fish (biggest is just over 5inches) I think they might have more trouble with bigger fish with bigger mouths though. You know how big your comets mouth is - chances are if its only 3inches it won't consider anything bigger than 2cm food.

    I have 6 comets who were feeder fish and now, three years later, they are beautiful and hardy. Also, it is good karma to rescue them! These comets are now 6 inches long!
  • Twigman - 2010-10-30
    I was told that once the bigger fish recognize the smaller ones as fish, they leave them alone. The bigger fish will eat eggs, however. I started out with 3 Comets (about 9 in. long) and before I knew it, there were about 30 babies swimming around. This past spring/summer I gave away about 25 fish becaue I had too many. I also have several Koi in my pond. My pond is 585 gals. Catfish will eat eggs & smaller fish, & so will frogs.

    By far am I a fish expert, but I have had a comet goldfish for a little over a month now, and he/she has grown from about 2" to about 4" and seems to be doing great. The other 3 fish we bought (black moor, gold fantail, and dwarf bn pleco) have all died, and now the comet is lonely looking. They were all together in the same tank when we bought them, so we assumed they would live well together, which apparently was not the case after doing a little information digging... From what I've seen, if they can eat it - they will, and maybe you could try finding a bigger comet...check maybe Wal-mart (if you have one near you). Good Luck

    Can you tell me how to breed my comets I have 1 goldish whitish and 2 orangeish whitish.
  • jason - 2010-12-11
    Your comet will just chase away the other and after three or 4 days they will get used to each other.

    I started off with 5 comet fish in a cow and horse trough last spring and the end of the summer I removed about 60 of their offspring into a diffrent cow trough. They say each female lays up 2 a thousand eggs so maybe they did eat some of their young but It was not as I'd been told. I even put one of the mamas in the same trough as I put the off spring. There was also many diffrent sizes of off spring.

I just bought about ten comet gold fish. One of them stopped eating and began to swim to a corner. Every time I removed him from the corner, he went right back to it. He stopped eating and eventually died the next day. All the other fish seemed to be fine. However, now another fish is sinking to the bottom and his gills stop moving for a period of up to one minute. Then, he flais a bit and sinks back to the bottom. Is this some type of sickness?

jason - 2010-12-11
How can I tell if my comets are male or female cause I really want to breed them?

    I have a white comet fish (it actually looks more silver), but based on the information I've come across while searching for a tankmate, I believe they live around 7 years and up to 14 years or longer if they are provided with optimum conditions....Good Luck. Just a side note - I have recently seen that even just ONE full grown comet fish can end up needing around a 55 gallon tank.
  • Chantal-Texas - 2010-11-21
    It takes a lot of experience to handle these. They are not the easiest fish to keep. I have had 5 now for five years. When they are gone I will never ever replace them. I have an Oscar and he is much cleaner and easier to keep. I would suggest not getting comet fish. I have nearly 40 yrs experience with all kinds of fish. But never comet or Koi would I ever get again.
  • Johnathan Ho - 2010-11-25
    I have 4 comet goldfish. I bought them in different times. The oldest one I have was since 2001.
  • jason - 2010-12-11
    If you take great well of your comet and feed them what they usually eat...they will usually live from 15 to 20 years. The longest that ever lived was 25 years old.
thom - 2010-11-21
I was wondering how to breed my comet goldfish I have 1 gold-ish white-ish comet fish and 2, orange-ish white-ish comet fish?

Annette - 2010-09-29
I have 4 Comets in a large outdoor pond. I am finding that I have to sell my home and move to an apt. Can I move the fish from the pond to a tank so that I can take them with me?

Linda B. - 2010-09-26
Hello there... Thank you so much for this web site! We are total novice comet keepers! Earlier in the summer we got 6 of the comets to put in our two rain "barrels"... sort of huge plastic tubs really... (3 in each one) to combat the mosquito larvae. It was a pretty good success all summer until a raccoon managed to get in about a month and wipe most of them out. I added fresh rain water every day to create bubbles, and then changed the water when it rained. Everyone seemed so happy until the raccoon came and the comets seemed happy to gobble up the larvae. Now we have just bought a nice aquarium to have the one survivor and his six new friends entertain us inside through the winter. Does anyone have any success stories about outdoor comets and their predators they could share with us? I am hoping we can put them back out again next spring.
