Emperor Tetra (Nematobrycon palmeri)
The Emperor Tetra has a genuinely majestic appearance, and an affable personality to match.
This species is peaceful, active and tranquil and rarely shows aggression, though the male will compete with other males. It can be kept with many different species but avoid putting it with more abundant species, or it may be seen as food. It will fare much better when in the company of its own kind though.
The original Emperor Tetras are royal blue and purple and vibrant yellow, which shifts back and forth and shimmers. They also display a stripe that blends out into purple or blue that lightens near the fins and tail, which are yellow.
The Emporer tetras come in 4 other varieties which include Rainbow, Blue, Black and Red.

What to feed the Emperor Tetra
Emporer Tetras will accept dried foods of a suitable size, but they will need a variety in their diet.
Daily meals of small frozen and live foods such as Artemia, Brine shrimp, Daphnia and similar, will not only encourage this species to breed, but it will also give the best colouration for this fish.
How to Breed the Emperor Tetra
The Emperor Tetra, when paired off, will breed with little to no help necessary.
Move them to their own tank with dim lighting, soft acidic water and feed them live food.
Provide a spawning mop or some dense floating plants for them to place their eggs, alternatively; you could put some mesh on the bottom of the tank that will be large enough for the eggs to fall into but small enough so that the adults can not get to the eggs.
Emporer tetras will only release a few eggs at a time so it could take several hours as soon as the eggs are noticed its advisable to remove the adults to avoid them consuming their spawn.
If you are unable to see any eggs after a couple of days, this means it has been unsuccessful therefore you will have to remove them and try again with a different pair.
