how much glofish can be kept in a 1 gallon tank?

GloFish (a genetically altered version of zebra danios) are very active fish and need to be kept in a large tank, preferably at least 20 gallons. Also, they are schooling fish, and are happiest in groups of 5-6 or more. There is no type of fish can live in a 1 gallon tank. None. I'm sorry, but if you want to have happy fish, you're going to have to get a larger tank. Also, to keep GloFish, you'll need a heater as well. Good luck and thank you for wanting to learn about your fish before you put them in a tank.

Sorry to have to say, but no, it won't do.

They really need to be in groups of at least 5-6 (being basically a zebra danio), and in far larger aquaria.

Ideally, a 10-15 gallon tank is the minimum for 6 of these little guys, but the bigger the tank and hte bigger the group, the better.

Unfortuantely, no fish whatsoever can thrive in a "tank" so small. If you want a really small tank, get a 5 Gallon (minimum) and have a lone male betta fish. They develop wonderful personalities, and are beautiful to look at. They do require a heater, as they are tropical fish, as do the glofish, as they are subtropical (meaning that if you lived in a warmer place you could probably manage without a heater, but it would be a good idea to have one if you didnt). Remember that all fish need filters, too, to keep their water clean. An aerator is always a good idea, but not essential, particularly as many filters will aerate as well, and rectangular tanks usually have sufficient surface area for a good level of oxygen transfer.

Whatever you do, ensure that you are prepared to care for your fish fully, including regular water changes. For example, if you got a 5 Gallon and a betta like my example, you would more than likely need to carry out 20% water changed weekly.

Best of luck and hope I helped =)

No that will not do. A one gallon tank is not suitable for any fish due to it's incredibly insufficient size.

GLOfish are schooling fish and so should be kept in groups of at least 6, and are very active. Their minimum tank size is considered 20 gallons.

Zero.

GloFish are genetically modified zebra danios. They have identical needs. Groups of 6 and at least a 15 gal tank.

Your 1 gallon tank is at best temporary. As goldfish grow and the grow fast you'll need a 5 gallon tank with filter like right now. That will do for couple of years. I have a 55 Gallon with 8 goldfish and due to their growth may have to sale a couple .

1gallon tank is so small.glofish should be in a 10gallon tank or higher.in a 10gallon you can only get like 4-6
