How to feed the Bucktooth tetra?
The Exodon paradus or the Two Spotted Exodon is an omnivorous fish. Thus, all kinds of food can suit it: dry, frozen or fresh. For a beautiful shape, vary its meals as much as possible, both in terms of content and shape! In any case, the basic diet will be composed of proteins such as worms, shrimps...
Particularly voracious, it is capable of subjecting its roommates to very great food competition. Indeed, it literally throws itself on food. In case of maintenance in a community aquarium, make sure that all your fish eat enough.

Behavior
What kind of behavior does the Bucktooth tetra have?
It has a very bad character: it is very aggressive and lively. It is gregarious in nature, a group of at least 15 individuals in 200 L / 44 Imp Gal / 53 US Gal is the minimum to be expected for this restless species that likes wide open spaces.
In a community tank, it will behave like a large predator, no more and no less.

Who can live with the Bucktooth tetra?
Given its strong character, specific aquarium maintenance is highly recommended.
If you still wish to associate it with other fish, be very careful and very careful about the species you choose to avoid disasters. Globally, the Exodon does not cohabit well with other species. To begin with, it does not tolerate at all the presence of fish with a silvery or too shiny colouring. They will probably be put to death. Choose rather dull fish to maximize compatibility. Territorial fish are also to be banned because the Exodon will become aggressive sometimes to the point of violent combat. Fish with large sails are to be completely forgotten: Guppy, Bettas, Scalarlet...
Same for the Molly, Platy, Gourami, Corydoras which will also be victims of the aggressiveness of the Exodon.
In any case, the Exodon must be the last one to arrive in the community aquarium. Indeed, any fish arriving after him will be considered as food.

How to breed the Bucktooth tetra?
Rare bredding but already arrived in aquariums.
First thing to do: differentiate male and female. It's quite easy, males are thinner than females.
To optimize the success of your reproduction, plan a secondary tank with a few plants and a lid because this fish can jump out of the water. At the bottom of the tank, install a grid so that the eggs are protected when they fall to the bottom of the tank. To do this, the mesh size must be large enough for an egg to pass through, but small enough so that the fish cannot pass through. Fill this aquarium with fresh, slightly acidic water.
Isolate the couple you have selected for breeding in this aquarium. To trigger spawning, make a large water change (about 40% of the volume) with slightly warmer water if possible. After spawning, return the adults to their living aquarium.
The eggs hatch after 36 to 72 hours. Unfortunately there will be cannibalism among the fry.

Which aquarium for the Bucktooth tetra?
An aquarium imitating the Amazonian biotope will be perfect for the Exodon. The basics of this biotope can be summarized as follows:
- lots of plants. However, leave enough room for swimming. To do this, plant your plants in a U-shape in the aquarium (on the bottom and sides). The presence of many plants will calm the fish somewhat and provide hiding places for potential roommates.
- Soil: sand or fine gravel strewn with a few pebbles. Dark soil promotes the fish's sense of security and brings out their colouring. For a more natural look, line the floor with dried tree leaves (catappa, oak, beech...).
- decor: roots or branches of driftwood
- peat filtration for black water typical of this biotope
Cover your aquarium well because the Exodon paradoxus is a jumping fish.
