Looks how to spot one

Elongated, torpedo-shaped scaled characin

A long, streamlined fish with a pointed head and an upturned mouth. Its pale peach to pinkish body carries bold black lengthwise stripes, the middle one curving into an arch under the dorsal fin, and the fins are tinted red. Mature females are slightly larger and rounder.312

Colourspale peach to pinkblack stripesred fins3

Personality what they are like

Gets along with peaceful medium to large fish such as robust characins, plecos and calm cichlids. With its own kind it can be quarrelsome in small numbers, so keep either one or a group of six or more.1

Daily activity how busy a day looks

Swims at a head-down angle and spends much of its time grazing on rocks and wood. It comes from fast-flowing rivers, so it enjoys good water movement and swimming room.1

Grooming and care the hands-on bits

Suggested ranges: about 20-28 C (FishBase gives 22-28 C), pH 5.5-7.5 (FishBase gives 6.0-8.0), hardness 1-18 dGH. Provide good filtration, oxygen and flow, and a lid.12

Home where they are happiest

Tank of at least 120 cm length (about 108 litres for one fish, larger for a group) with rocks, wood, some current and space to swim.1

Food basics what goes in the bowl

An omnivorous grazer that eats algae and small invertebrates. Offer algae wafers, blanched vegetables such as spinach and cucumber, and live or frozen foods.12

Company who they like around

Can be kept singly, or in a group of six or more in a big tank to spread out squabbles.1

The story where it all began

One of the earliest fish formally named, described by Carl Linnaeus in 1758. In the wild it lives along the rocky edges of fast rivers, picking food off stones. In 2008 three species once placed in its genus were moved to a new genus, Petulanos.12

Fun facts for the dinner table

  1. 1

    The genus name comes from Greek for 'up mouth', after its upturned mouth.2

  2. 2

    It usually swims at an angle with its head pointing down, which gives headstanders their name.1

  3. 3

    It was formally named by Carl Linnaeus in 1758.2

  4. 4

    In the wild, males guard the nesting site in dense vegetation.2

Owner questions the things everyone asks

How often should I feed my Striped Headstander?

Feed your Striped Headstander small amounts once or twice a day. Furry Diary's starting plan suggests daily feeding to match its grazing nature. Furry Diary plan

What does a Striped Headstander eat, and what should it never eat?

It eats algae wafers, blanched vegetables like spinach and cucumber, and live or frozen foods. For what to never feed, specific unsafe items are not listed here, so ask your vet or a good breeder for guidance.12

How much space does a Striped Headstander need?

Your Striped Headstander needs a tank at least 120 cm long, about 108 litres for one fish, and more space for a group. This gives it room to swim and graze.1

What temperature, light or water does a Striped Headstander need?

Keep the water between 20-28 C, pH 5.5-7.5, and hardness 1-18 dGH. Provide good filtration, oxygen, water flow, and a lid to prevent jumping.12

How often should I clean a Striped Headstander's home?

Furry Diary's plan suggests a weekly 25% water change, weekly water tests and glass cleaning, and rinsing the filter monthly in old tank water. This keeps the environment healthy. Furry Diary plan

Can a Striped Headstander live with others?

Yes, it gets along with peaceful medium to large fish like robust characins, plecos, and calm cichlids. Keep either one alone or a group of six or more to reduce squabbles.1

How long does a Striped Headstander live?

Lifespan information is not provided here. It varies by care and species, so ask your vet or a good breeder for a typical range.

Can I handle a Striped Headstander?

Striped Headstanders are not fish to handle. They are sensitive and best left in the water to avoid stress and injury.
