GloFish is a patented and trademarked brand of genetically modified (GM) fluorescent fish.

Several color varieties of GloFish are currently available here in our store, and they are all very cool.

The ancestors of our GloFish had DNA from a different animal spliced into their DNA.

So these GloFish have not been dyed or injected with dye.

Above: Shown in the picture above is a premium quality Galactic Purple GloFish Rainbow Shark.

As you can see, it's pink with bright red fins.

This fish was about 2.5" long and swimming in one of our aquariums, when one of us snapped this picture.

Comments: This is a Premium Pet Fish, and we never see Premium Fish like these in any of the live fish stores or in the other online fish stores that we visit.

These Premium Pet Fish are more energetic, hardier, and have brighter colors with a beautiful metallic sheen.

Origin: The ancestors of our Rainbow Sharks originally lived in Thailand, Laos and Cambodia, but now they're raised on fish farms and found living in aquariums throughout most of the world.

Maximum Size: In aquariums they can grow to be about 6" long, which is a nice size for bigger home aquariums.

But long-ago a friendly fish farmer in Florida sent the Bailey Brothers, DrTom and Nevin, a box with 6 or 8 gigantic Rainbow Sharks that were measured at over 9" long.

The Baileys wondered if it might be a similar but different species.

They found out that the fish probably were Rainbow Sharks that had grown up in a huge outdoor pond or concrete vat with lots and lots of excellent food, high water quality, and tons of tenda' lovin care.

Behaviors: this is a very active swimmer that's aggressive.

It's especially aggressive to other Rainbow Sharks and to other fish with a shape similar to it's shape.

It's important to always keep the aquarium tightly covered, because Rainbow Sharks are very skillful jumpers.

Compatibility: Some recommended tank mates include Bala Sharks, Clown Loaches, Barbs, Danios, Gouramis, and many other medium size aquarium fish.

Temperature: Rainbow Sharks can live pretty well from about 70 to 80-degrees F., but they're probably most comfortable at about 75 to 78-degrees F.

Feeding: Premium Fish Food Flakes when small and Premium Pellet Food when larger.

Water Conditions: Rainbow Sharks seem to be tolerant of a wide range of water conditions.

Probably a pH of about 7 with moderate hardness is best.

Most water in the US has a higher pH and is harder but seems to be OK, so it's probably best NOT to adjust the pH or the hardness of the water.

Here in our facilities the water is hard and the pH is usually about 7.8. We ship them in this water.

Aquarium Size: When young and less than 3" long, it's probably best to house one in at least a 30-gallon tank, but bigger is better.

Later when they grow bigger, they'll need 50 to 60-gallon aquarium.

Decor: Rainbow Sharks do not need gravel, and a layer of gravel more than 1/4" thick will usually fill with bits of uneaten food that will contaminate the water.

Live Plants: are beautiful and improve the water quality.
