Neon Tetra (Paracheirodon innesi)

Picture incomming!

A Neon Tetra, picture from

Neon Tetras, the most popular fish to keep in todays tropical fish tank! With their peaceful nature, vibrant coloured bodies and inexpensive cost, why wouldn't you want them?

Size:
1.5", 4cm
(10g)40L or more, depends how many you want.

Compatability:
As Neons are very peacful, anything else with a similar nature.
Nothing larger, as they are very commonly eaten by larger fish (Synodontus, larger cichlids ect)


Sexing:
Difficult, you must look at the belly of the Neon. Females will have a larger belly (holding eggs), which would also mean their blue line would be distorted, not lookign straight. As a male wouldn't be holding eggs, the blue line will be straight.


Feeding:
General flake food will be fine, they're small fish so they don't eat much. Be careful about overfeeding!!


Water quality:
PH: 5.5-7.5
DH: 1.0-25
The above stats depend entirely on where they're bred, as these fish are bred heavily for public demand, they may be able to go into higher PH water easily. If you want to play it safe I wouldn't go higher than a PH of 7 (DH of 10).


Freshwater Tropical.


Breeding:
PH 6-6.5
DH 1-2
Temp 22-24C

Breeding these fish can be difficult due to not being hardy fish currently.
They require a low light aquraium (Preferably dark / semi dark) as the eggs are light sensitive. . Feed the females on high quality foods such as live worms / blood worms ect, which would hopefully get them to start producing eggs as they have a increase of available energy. Have a group of 2-1 male ratio (refer to sexing as above). Leave them in there for around 24 hours, you should see eggs being scattered, and remove. Reccomended to use plants, such as Java Moss or any other finer leafed plant to hold the eggs.

One laid, the eggs will take 1 day to hatch, and a further 3-4 days to be free swiming, which you can start feeding them infusoria/rotifiers, then in 4 weeks max, you can start them on Brineshrimp. This does depend on how fast they grow, so you may want to use a combination of both after two weeks.


Special requirements:
The Neon Tetra we know today definitely isnt the same neon tetra we would of seen in the wild 100 years ago. There's been a very high demand on the numbers of these fish as they are brightly coloured, small and peaceful. Due to this high demand, these fish have been bred to a point where genetically they're weaker than almost every other fish in the aquarium. Due to this, you have to take caution when purchasing them. When picking, follow these steps:
-Brightly coloured in LFS; I wouldn't purchase them if they just arrived, as they're very stressed and prone to death / sickness if moved to another aquarium.
-Buy groups, these are schooling fish, 6 is a minimum. More is definitely better.
-Keep a eye on your levels, a small ammonia spike may knock a couple of these guys out. Be careful, especially if they're your first fish (Such as feeding every two days instead of everyday. Only if you haven't pre cycled your tank).
-Clean waters makes them happy!!:)

That's pretty much Neon Tetras in a nutshell, feel free to leave a comment and I'll answer it when I can!
