Platinum Hatchet
Thoracocharax stellatus
The Platinum Hatchetfish is a distinctive, deep-chested surface dweller known for its extraordinary jumping ability. They are obligate top-level swimmers that require a strictly sealed, tight-fitting lid to prevent escape. Floating plants are highly recommended to help them feel secure and minimize skittishness. They must be kept in schools to thrive.

Platinum Hatchet Care Guide Summary
The Platinum Hatchet, scientifically known as Thoracocharax stellatus, belongs to the Characins family group. Adults reach a maximum size of approximately 7 cm and have a compressed body shape with a moderate growth rate. Classified as peaceful, this species primarily occupies the surface zone of the aquarium and produces a low level of biological waste.
To thrive, the Platinum Hatchet requires a freshwater only aquarium with a minimum volume of 110 litres and a tank length of at least 90 cm. Water temperature should be maintained between 23°C and 28°C, with a pH range of 5.5–7.5 and a general hardness of 1–12 dGH. A moderate water flow is preferred.
The Platinum Hatchet is a rewarding species to keep, provided its core environmental needs are met. The Platinum Hatchet is typically available in one standard form.
Platinum Hatchet Habitat Setup
When setting up an aquarium for the Platinum Hatchet, a moderate water flow best suits their natural preferences. Because this species occupies the surface zone, the aquarium layout should prioritise adequate surface area with floating cover to make them feel secure near the waterline. Useful additions include floating plants to diffuse overhead light and create shaded areas. Keepers should note that a tight-fitting lid is essential, as this species is a known jumper.
Platinum Hatchet Compatibility Notes
Classified as peaceful, the Platinum Hatchet is a schooling species that feels most secure in a sizeable group, where natural shoaling behaviour reduces stress and brings out their best colours. Selecting tankmates that favour different water layers from the surface zone can help reduce competition and territorial overlap.
Who Platinum Hatchet Is Actually For
Platinum Hatchet is best for a fishkeeper who wants a species that can settle into a calmer community setup and can provide a keeper who can commit to a proper group of at least 6. It makes the most sense for a hobbyist who will actually build around its needs, especially plants.
The most common mistake is buying Platinum Hatchet for looks first and only later discovering how its adult size, behavior, or bioload changes the whole tank plan. Another frequent problem is underestimating its social needs. A token pair or trio often behaves very differently from a real group.

Fish Similar to Platinum Hatchet
Marbled Hatchetfish
Carnegiella strigata
A uniquely shaped, peaceful surface-dwelling characin famous for its deep, keeled belly and incredible jumping ability. In the wild, they can leap from the water and 'fly' short distances using their powerful pectoral fins to catch insects or escape predators. A tight-fitting lid with absolutely no gaps is mandatory. They require floating plants to feel secure and must be kept in schools.
Silver Hatchetfish
Gasteropelecus sternicla
A uniquely shaped characin with a deep, keeled belly adapted for surface dwelling. Known as 'flying fish', they possess powerful pectoral fins used to leap from the water to catch insects or escape predators. A tight-fitting lid with absolutely no gaps is mandatory. They are peaceful schooling fish that require open surface swimming space and floating plants to feel secure.
Finger Fish
Monodactylus argenteus
The Silver Mono, or Finger Fish, is a stunning, fast-moving schooling fish known for its shiny, diamond-shaped body. They are euryhaline; juveniles inhabit freshwater or brackish estuaries, but adults require high-end brackish or full marine setups to thrive. They are active, voracious eaters that must be kept in groups to curb fin-nipping and internal aggression.
Scissortail Rasbora
Rasbora trilineata
A highly active, streamlined schooling fish named for its deeply forked tail with black and white bands. As they swim, the tail stripes create a scissor-like opening and closing motion. While very peaceful, they are fast, restless swimmers that require long aquariums to thrive and may outcompete slower or shy tank mates for food.
Bala Shark
Balantiocheilos melanopterus
Despite its name, the Bala Shark is a peaceful, schooling cyprinid. They are extremely active, fast swimmers that grow very large and startle easily. They are notorious for injuring themselves by crashing into the aquarium glass if kept in small tanks or easily spooked. They must be kept in groups and eventually require massive, custom-sized aquariums.
Gold Spot Pleco (L001 / L022)
Pterygoplichthys joselimaianus
A robust, highly attractive sailfin pleco featuring a dark body adorned with striking gold or yellowish spots. Like other Pterygoplichthys species, it grows very large and produces a massive amount of waste. While peaceful toward mid-and-top dwelling fish, it can be territorial with other large bottom dwellers. It requires driftwood in its diet for proper digestion.
