Rosy Red Minnow
Rosy Red minnows are mostly sold as feeder fish in fish stores. Rosy Red Minnows are the fish that you'll see 500+ packed into a small tank. Because of these conditions, they are often disease ridden - fungal infections, bacterial infections, and parasites. They come in different color variations - rosy reds being pink, and the natural fat head color of brown.
If being used as a feeder, the Rosy Red Minnow need to be quarantined, and medicated so that it will not pass on disease to your larger fish. It is best to breed your own rosy reds if you plan on using them as feeders.
If you plan on keeping them in a community aquarium they should also be treated for parasites. They make wonderful additions to both cool water and tropical aquaria due to their very hardy nature. They will school, so keeping a minimum of three is best with a ratio of one male to two females.
Rosy Reds are a popular pond fish, often used as a dither fish for fancy goldfish and koi. In a pond they will keep the insect larvae to a minimum, but will also eat goldfish and koi pellets. They are active even when the pond freezes over in the winter, and can often be seen swimming under the ice.
The Rosy Red Minnow are a very inexpensive, hardy fish. They are a great addition to someone who wants a cool water tank but does not have the room to house goldfish. Or to someone who just wants something different in their tropical community tank.
The male Rosy Red Minnow will care for their eggs and fry. Their breeding behavior is somewhat similar to cichlids. Overall this is a very underappreciated fish that would make a great addition to just about any aquaria. It is a great fish for someone wanting to try their hand at breeding egg layers for the first time.

The Glofish were genetically modified with the purpose to detect environmental pollution. Scientists were able to inject a fluorescent protein gene (from marine organisms) into the zebra danio embryos to create the glofish.
