At a glance the quick version
Looks how to spot one
High-backed, scaled characin
A deep-bodied fish with a strongly arched back and a small head. It is marked with about eight dark vertical bands over a lighter base, giving a marbled look that varies from fish to fish. A keel runs along the belly behind the pelvic fins. Adult females are deeper-bodied than males.1
Personality what they are like
A lively fish that suits a large tank with robust cichlids, characins and catfish. It can nip fins, so slow fish with long fins are not ideal companions.1
Daily activity how busy a day looks
An active fish that swims head-down while picking food from the bottom, and needs plenty of room to move.1
Grooming and care the hands-on bits
Adaptable to a wide range of conditions. Suggested ranges: about 20-30 C (FishBase gives 23-27 C), pH 5.5-7.5 (FishBase gives 6.0-7.5), hardness 1-15 dGH. Keep filtration strong and water clean.12
Home where they are happiest
Tank of at least 120 cm length (about 108 litres for one fish, larger for a group) with wood and rocks; it will eat soft-leaved plants, so choose tough plants or none.1
Food basics what goes in the bowl
An omnivore that eats worms, small crustaceans, insects and plant matter. Feed quality dried foods, frozen bloodworm and daphnia, and plenty of vegetable matter such as spirulina-based foods.12
Company who they like around
Does best as a group in a large tank.1
The story where it all began
Named by Albert Guenther in 1868, it lives in muddy main channels, side streams and backwaters that flood each season. Its genus contains only two species and is set apart by the keel on its belly.12

Owner questions the things everyone asks
How often should I feed my Marbled Headstander?
Feed your Marbled Headstander small amounts once or twice a day. Furry Diary's starting plan suggests feeding daily, offering only what they can eat in a few minutes to keep water clean.1 Furry Diary plan
What does a Marbled Headstander eat, and what should it never eat?
This omnivore enjoys quality dried foods, frozen bloodworm and daphnia, plus plenty of vegetable matter like spirulina-based foods. What it should never eat varies by individual; ask a vet or good breeder for specific foods to avoid.12
How much space does a Marbled Headstander need?
A single fish needs a tank at least 120 cm long and about 108 litres, but a group requires more space. They are active swimmers and need plenty of room to move head-down while foraging.1
What temperature, light or water does a Marbled Headstander need?
They adapt to a wide range: temperature 20-30°C (23-27°C from FishBase), pH 5.5-7.5 (6.0-7.5), hardness 1-15 dGH. Light needs are not specified, but strong filtration and clean water are important.12
How often should I clean a Marbled Headstander's home?
Furry Diary's plan recommends a weekly water change of about 25%, along with weekly glass cleaning and water testing. Rinse the filter monthly in old tank water, never tap water. Furry Diary plan
Can a Marbled Headstander live with others?
Yes, they do best in a group in a large tank. Good tankmates include robust cichlids, characins and catfish, but avoid slow fish with long fins as they may nip fins.1
How long does a Marbled Headstander live?
Lifespan varies depending on care and conditions. For a more accurate estimate, ask a vet or a good breeder familiar with this species.
Can I handle a Marbled Headstander?
Handling is not recommended for fish; it can cause stress and injury. If you need to move them, use a soft net and ask a vet for guidance.
