What are Glofish, and what is the best Glofish tank?
Glofish (sometimes spelled ‘glow fish’) are genetically engineered fluorescent fish that are patented and trademarked. The original, long-term goal was to modify fish so they would fluoresce in the presence of toxins.
Scientists in Singapore were trying to develop this new type of fish to help detect toxins in the water to help protect people using the local waterways. However, the first step was to engineer a fish that would fluoresce all the time.
The GloFish is the result of that undertaking.

Some misconceptions still remain regarding how the Glofish fluoresce is achieved.
Some think the fish are dyed or injected. This, of course, is incorrect.
Instead, these fish have had their appearances modified at the genetic level – it is a bio-luminescent gene that causes the glow. Further, only their skin is fluorescent, the rest of their internal systems are not affected.
To enjoy the fluorescent effect, you can simply view them under blue light.
However, they are also rather bright under typical white light. To really enjoy the best possible effect, it is recommended to view the fish under a black light in a completely darkened room.
Although this fish is quite remarkable, its care is not. For instance, in terms of the size of the tank or the required amount of food, they are decidedly unremarkable.
Their needs are similar to other freshwater fish.
Additionally, they live up to five years of age, much like other aquarium fish.

Different Breeds Of Glofish
GloFish come in six different breeds of common fish varieties.
The shark is an smaller, elongated fish with sharp, narrow fins.
The Glofish shark is not actually a shark, it just looks a bit like one! It’s actually a minnow, and they are the largest variety of Glofish.
The Barb appears much like the Perch or traditional goldfish.
It has a smooth, rounded diamond body and a barbed dorsal fin.
Long-fin Glofish Tetra
The long-fin Tetras are exotic in appearance with their tails, dorsal, and anal fins stretching out in a sweeping elegance.
More striking is the whisker-like pelvic fin that sweeps downward like a kite tail.
Danios are small goldfish whose appearance is that of a sardine.
They are compact, allowing them to dart when spooked.
The common Tetra is shaped much like a piranha.
It is circular with a bulging belly. The dorsal fin is prominent, overshadowing in size the soft dorsal fin, which, comparatively, is barely visible.
How Many GloFish Per Gallon?
As a rule, GloFish should be allowed up to three gallons per fish.
That being said, for these fish, more space is better.
For example, although they prefer to exist in groups, they often exhibit aggression toward one another in cramped quarters.
A small five-gallon tank, for instance, you should have no more than two fish.
For a larger 30 gallon fish tank, you can safely maintain eight to 10 fish.
You may also want to consider these Glofish kits as a way of getting everything you need in one hit!

Glofish brand food can be purchased, though your fish will also eat the regular food that say a tetra, danio, or barb would eat.

There is a large range of Glofish Decor available, such as the Fluorescent Plant.
