Why do GloFish die?

Answer 1

The usual reason is not being looked after properly. They are tropical fish and need a temperature of about 75F plus one fish needs to be kept in at least 2 gallons of water and should have a filter running 24/7 and a 50% water change every week. The basic rule is "1 inch of fish needs at least 1 gallon of water".

Answer 2

Glofish are in reality only Zebra danios (Brachidanio rerio) that have had a jellyfish gene added artificially in a laboraory in order to make them glow. They need to be kept at the same temperature as most other tropical fish at around 75F to 80F, and the basic rules apply to them too.

The basic rules for keeping any kind of fish sucessfully are. :- 1 inch of fish needs at least 1 gallon of water. :- Every tank must have a permanently running cycled filter. :- Every tank must have at least 50% of its water replaced every week. If you stick to the above rules your fish will stand a chance of survival.

If you miss out on any of the above, I can guarantee that your fish will be constantly getting sick and dying before they should.

Where does the fluorescent color come from?

The fluorescent color in our fish is produced by a fluorescent protein gene, which creates the beautiful fluorescence that can be seen when looking at the fish. The fluorescent protein genes occur naturally, and are derived from marine organisms.

Exactly how is the fluorescent protein gene added to the fish? Every line of GloFish® fluorescent fish (i.e., GloFish® Starfire Red® Zebra, GloFish® Electric Green® Zebra, and GloFish® Sunburst Orange® Zebra) starts with a single fish. The process begins by adding a fluorescence gene to the fish before it hatches from its egg. Once the gene integrates into the genome (i.e., genetic code) of the embryo, the developing fish will be able to pass the fluorescence gene along to its offspring upon maturity. Because of this, the gene only needs to be added to one embryo; from that point forward, all subsequent fluorescent fish are the result of traditional breeding.
