These active fish are eating machines that put out a huge amount of waste.Īs that waste accumulates in the aquarium, it will break down and begin to put off ammonia (NH 3). You may want to look into getting a canister filter. Good filtration is absolutely critical when you’re keeping comet goldfish. Please, keep goldfish in an appropriately sized tank with a filter. THERE IS NO SPECIES OF GOLDFISH THAT CAN SURVIVE LONG TERM IN A GOLDFISH BOWL. I’m not saying it’s impossible to keep them in a tank, I just think it’s easier to have them in a good sized pond outside instead of maintaining a massive tank in your living room that can only house three or four fish.Īll species of goldfish get fairly large and need a lot of tank space and filtration. In fact, if at all possible, I would recommend keeping comets in a medium to large pond instead of an aquarium. I know, that seems an awful lot of tank space for just a few fish, but they really do need that much room. So, two comets should be kept in a 125 gallon (473 liter), three should be in a 175 gallon (662 liter), and so on. I recommend keeping a single comet goldfish in a 75 gallon (284 liter) tank.Īnd if you want to keep a group, you need to add another 50 gallons (190 liters) per fish. Not only are they large, but they are also very active fish that puts off a lot of waste.Ĭomets swim almost constantly and so they need a large area to move around in. They can easily reach lengths of 12 inches (30 centimeters).

These fish are very large when they reach adulthood. The most important thing to consider when it comes to comet goldfish is space.

How to Set Up a Comet Goldfish Tank Tank Size The common goldfish was originally bred from the Prussion carp ( Carassius gibelio). Murlett selectively bred common goldfish to create this special breed of goldfish that is slimmer and has a large, deeply forked, single tail. They were first bred by Hugo Mulertt, a government worker in Washington, D.C. Comet-tailed goldfish first appeared in the aquarium trade in the late 19th Century. The comet goldfish is not a naturally occurring species. A comet’s tail is usually the same length as its body. They have a large, flowing tail that really stands out compared to a common goldfish. And the most noticeable difference, comets have much larger, showier fins.
