Appropriate Home. An aquarium with 15 gallons or more water, a small exterior power filter with a BIO-Wheel, a layer of gravel at most 1/4 thick, and an aquarium heater adjusted to between 75 and 80 degrees F.
Recommended Diet. Floating Flake Food for Tropical Fish.
I feed these small fish a few Black Worms every other day. Just two or three worms for each fish. Usually they swallow half of a worm and swim around with the other half of the worm hanging our of the their mouths for a while.
Compatibility. Neon Tetras should be kept in a school with at least 6 Neons and 10 is better. The same is true for Glow Light Tetras and Black Phantom Tetras. These are all schooling fish that live best in a school with their own species.
Here is a list of fish that will do well with Neon Tetras: Glow Light Tetras, Black Phantom Tetra, and Harlequin Rasboras.
Here are some more good tank mates for Neon Tetras: White Clouds, Glass Fish, Corydoras Catfish, Fancy Guppies, Honey Gouramis, and a few Ghost Shrimp.
Neon Tetras will usually not do well in the same aquarium with Large Tetras such as Black Neon Tetras, Black Skirt Tetras, Serpae Tetras, and other similar fish that are too aggressive for Neon Tetras.
You may have gotten advice that Neons will do well with most other types of Tetras, but our experiences with these fish in our aquariums shows us that they won't, and for that reason we have divided the Tetras into two groups called the Smaller Tetras and the Bigger Tetras.
