Blackout Comet Goldfish

You might not find too much about a Blackout Comet from a Google search. Probably because there’s not a lot that has been posted about it. Not much is known about this type of goldfish. We do know however, that it is an Israeli breed, coming out of the oldest breeding farm in Israel, Hazorea Aquatics.

It is a new type of goldfish and as such, the breeder remains tight lipped about the genesis of this particular goldfish. And understandably so. The hypothesis is that the selective cross-breeding program involved Black Moor and Comet goldfish.

You might come across a black comet from time to time, but it isn’t a Blackout Comet. Some pond or tank keepers might be excited to find they have a black-colored comet, but then become disappointed to watch it fade and eventually turn red or gold.

That’s because ordinarily the black coloration is not permanent, and is usually as a result of “ammonia burn” that happens in transit. That is not true of a Blackout Comet. Thanks to the selective breeding, it will remain black for the duration of its life.

  1. i have MANY BLACK GOLD FISH? how can i tell if they will true black or change?
    some are 4-6 in long,how big can they get?
    thank you

    1. goldfish (common and comets) get 18 inches long and unless you actually buy a black out comet you will never know if they will change however a good clue is how dark they are the darker they are the more they will likely stay black

  2. Can blackout comets reproduce? Or are they some sort of koi goldfish cross as some writers claim?

    1. Blackout Comets are not known to reproduce, as they are a cross breed, and therefore sterile.

    I purchased shubunkins from you and they spawned….lots of them! Lol 8 of the fribunkins are black….really black! They are about 5 inches and still black?

    1. Congratulations on the new spawn! Your Shubunkin Fry may remain black for some time, but are likely to change over their life time. They may even have a color change within their first months to a more speckled color. We hope you’ll enjoy them.

    4 yrs ago I was given 15 “baby” black Koi 2” in length. SOMEBODY had a spawning in their outdoor pond & was parceling them out. I got them home & saw they are not Koi. I had already placed them in my outdoor goldfish pond withseveal Sarassas 2” to 6”. The blacks have grown; they’re friendly & active. I have lost ONE to a bacterial infection but my fish & ponds are well-built & maintained. I have been disappointed that they have shown no inclination to spawn like my other goldfish do. As stated, the History I got was that they were the offspring of large black fish. Any thoughts?

    1. While we can not say with certainty your Blackout Comets, many of the fish of this variety can be sterile. This may possibly explain why you have not had them successfully spawn like your other Goldfish.

    1. Hello Teri,

      It will likely not be until next Spring before we see more Blackout Comets or Apricot Comets back in stock. lease kindly check back for availability at that time.

      Thank you.
