How many litres/gallons do two 1inch comets need?

Question

i will upgrade later

Answer 1

In an average 10 gallon tank, if well cared for and not crowded, they can grow up to about 4 inches (10 cm), while in a larger uncrowded tank they can grow larger generally reaching about 7 or 8 inches (17.78 - 20.32 cm). If kept in a spacious pond they can reach over 12 inches (30+ cm).

And just remember this rule for fish and tanks/ponds - !inch inch of Fish per 1Gallon of water aka- if you have 10 one inch fish, you need a 10 gallon tank. Or if you have two five inch fish, you need a 10 gallon tank.

That has good Comet Goldfish Info

Answer 2

10 gal to get started, they need about 10 gal a fish when they get bigger. You will want to do a 30 to 50 percent water change every week or test your water once or twice a week. Goldfish are dirty little fish and mess their water up fast. Happy fish keeping.

Answer 3

Comets need room.  Sure, while they are small they are great in a 10 Gallon per fish.  However, They do grow and get up to a foot long.

I can tell you from experience, these fish will grow big...I have had two in the past, at different times,One who grew and fit the tank with no issues...but when I moved him to a bigger tank, he exploded double his size.  As he grew...I found him a home with someone who had Comets and the room to care for this one.

I had another I rescued as a small fish and he ended up being 9 inches long before I adopted him out to a friend with a small pond.

I would, at the least have a 50 Gallon Tank for the 2 you are thinking about...if not more.  They will thrive well in a big tank.  Make sure you have excellent filtration, for these fish are opportunitic feeders, eating everything they can fit into their mouths...thus more waste.  I would consider an undergravel filter system with a Cannister Filter System to compliment each other.

UPDATE...One Strange Cookie has a great point.

2nd UPDATE...use whatever you have, but have a great filtration system...that is probably one of the most important things with GOLDFISH of any type...besides space...but as a younger small fish...its ok briefly to be in a smaller tank.  Just consider, of the 2 Comets I have had, one grew big in about 4 months...the other in the smaller tank who was moved to the bigger tank where he exploded in size...did this in a matter of a couple of months after moved to the bigger tank.

Best of Luck!

Answer 4

they grow fast and in an inadequate tank, will be stunted in a matter of months.... just get a 100gallon tank from the start =]

Answer 5

a 12 gallons 24X12X12 will be a good home for a moment just don't forget the filter.

Answer 6

Well since they grow so fast, it is best to start out with the right sized tank of 50 gallons. If you really want to spend 300$ and them a year or less later spand another 400-500$ on a 50 gallon tank feel free, it is your money! Well, once grown they need 50 gallons for 2, but I guess 25 gallons would be ok for a year, but no more.
