The fascinating GloFish has been genetically altered to give off a bright neon glow. The genes of this Zebra Danio have been altered with the genes of a certain anemone that features the illuminescence, and that is how the GloFish came about!
The Starfire Red GloFish was the first color releaed. They are hot pink with slightly lighter stripes. The top of the head may be lighter or slightly orangish in color.
The GloFish is just as hardy as a regular Zebra Danio and also features the same bluish striping. They are an active fish that will hang out around mid-water or upper water level. They are great for community tanks. Feed them a varied diet of flake, small pellet, and occasional small-sized frozen food.
The glowing coloration of the GloFish will not fade or change - it is within their genetic structure and will actually be passed on to their offspring should they spawn. To see them "glow" at their best, keep under blue "actinic" lighting. The colors will be bright under white lighting but will not "glow" as brightly.
Of the five fish I ordered (red, blue, green, purple, orange) this was one of the most colorful. I would recommend red, green, or orange for the full glow effect. 4 of the 5 fish I ordered died on day 6. The other was eaten during shipment. No refund on DOA because there was no fish to take picture of. I had my water was tested daily at my local fish store for Ammonia, Nitrate, Nitrite, and pH because my testing supplies hadn't arrived yet. All levels were fine and my new set up 29 gal. tank was far from being crowded with only these 5 fish. No refund on rest of fish because it was past day 5 of order date. I ordered 08.18.14. Maybe they were sick from the start and it was just a bad batch, but I will never order from here again.

I love this fish, especially to see him chase my glofis tetra and my swordtail while the product was shipped safely and the prices are even better.
Not Very Hardy 2/21/2013
These are beautiful little fish and very enjoyable to watch. However I don't think they are very hardy fish. I bought 5 to start a school in an already established aquarium, I have now had 2 fish die due to a fungus. No other fish in this aquarium have been ill and none have ever exhibited any signs of illness prior to this addition. I've done a lot of research on the GloFish line and have not found much by way of illnesses that they are prone too. Could just be that these fish are not as healthy as they should be.

This fish's arrival size is 1 inch in length. A really sweet schooling fish and the awesome factor is you can mix and match danios if their the same size. The danios swim back and forth at the top of the aquarium.
