How to feed the Beacon fish?
Omnivorous: all forms of food are accepted with preference for live prey. A varied diet will bring out its colors.
What kind of behavior does the Beacon fish have?
Species with a rather lively and slightly aggressive temperament. It remains nonetheless classified among the peaceful aquarium fish. Like all species of the genus, it is gregarious and must imperatively be kept in a shoal. Indeed, it will flourish much more in the company of its congeners. Conversely, in too small numbers, it becomes extremely nervous and aggressive.
Who can live with the Beacon fish?
A community aquarium is accepted but beware of shrimp. This is one of the best choices of Characidae for the whole tank. You can associate it with other species of the same size but it must be the only middle fish in the tank. Depth inhabitants such as Corydoras or small Loricariidae, or on the contrary surface species like most Gouramis will be good roommates. Small dwarf cichlids like Apistogramma will also be well matched.
Finally, avoid large fish like Scalar that could confuse them with their meal as well as fish with long fins like the Fighters for example.
How to breed the Beacon fish?
Breeding is possible but requires some experience in this area. Indeed, some conditions are essential for successful breeding. Place in a spawning tank (20 L or 5 US Gallons or 4 Imperial Gallons) equipped with a protective grid and thin-leaved plants such as Java moss, a male and a female. Temperature at 27°C or 81°F and KH at 4°.
Choose a place that is a little sunny in the morning but the aquarium itself will have to be very dimly lit. Filtering on peat and using osmosis water will be a plus. Separate the sexes and prepare the parents for spawning by feeding them abundantly with live prey. Select a beautiful male and the most round female and introduce them at night in the breeding tank. Spawning should take place the next morning. As soon as the eggs appear, remove the parents. The incubation lasts 24 hours and must be done in total darkness. The fry are raised in about 10 cm or 4 inches of water, and the water level is raised as they grow.
Fry food: infusoria, nauplies of artemia and cyclops.
Which aquarium for the Beacon fish?
Go for dim lighting. In terms of water chemistry, peat filtration is ideal for its balance and for maintaining low stable parameters.
For an Amazonian biotype aquarium, the scenery will consist of a substrate of river sand (as dark as possible), roots, rocks and tufts of scattered but abundant plants. Be careful to leave them enough swimming space.
For a more natural effect, line the soil with some dried leaves (beech or oak for example). You will replace these leaves as needed to avoid rot. These leaves will slightly tint water, this is the effect sought in a bin biotype like this one.
In a poorer setting, the Head and Tail Light slightly loses its colors.
Finally, you’ll notice that it likes to play in a moderate to strong stream.

This fish will be a very good choice for beginners: it is robust and inexpensive.
It owes its name to the two luminous red dots of its body: one is at the eye level and the other on the tail.
It differs from Hemigrammus ocellifer falsus by the presence of the dark stain behind the head.
Note that there is an Albino variety of this species.
