Introduction

The Red Base Tetra (Hemigrammus stictus) is a small, peaceful fish perfect for community tanks. Known for their striking red base coloration, they thrive in soft, acidic water and make an excellent addition to well-planted aquariums. Originating from the waterways of South America, these tetras are both beautiful and hardy, provided their basic needs are met.

Food and Feeding

Red Base Tetras can be a little picky when first introduced to a tank, but they adapt well to a variety of foods over time. Their staple diet should consist of high-quality flake food or pellets. To keep them healthy and engaged, supplement their diet with live or frozen treats such as brine shrimp, bloodworms, or daphnia twice a week. This diverse diet ensures vibrant coloration and overall well-being.

Origin

Native to South America, Red Base Tetras are commonly found in the freshwater streams and rivers of Guyana and Colombia. These habitats are characterized by soft, acidic water and abundant plant life, which should be replicated in aquariums for optimal care.

Sexing

Identifying the gender of Red Base Tetras is relatively straightforward. Females are slightly larger than males and exhibit a rounder, plumper body shape, especially when ready to spawn. Males are typically slimmer and may display more intense coloration.

Breeding

While breeding Red Base Tetras can be challenging, it is achievable with proper preparation. A separate breeding tank with soft, acidic water and a temperature of 25–26°C (77–78.8°F) is recommended. Include fine-leaved plants or a spawning mop where eggs can be laid. Females scatter their eggs among the plants, and the fry will hatch within 24 hours. Once the fry become free-swimming, feed them with Infusoria or rotifers. After about a week, they can transition to newly hatched brine shrimp.

Tank Setup and Care

To ensure the comfort of Hemigrammus stictus, create an environment that mimics their natural habitat. Soft, acidic water with a pH range of 6.2–7.2 is ideal. Add plenty of plants, driftwood, and rocks to provide hiding places and reduce stress. Subdued lighting enhances their natural colors and helps them feel secure. Maintain water temperatures between 23–26°C (73.4–78.8°F).

Behavior and Compatibility

Red Base Tetras are peaceful fish that get along well with other similarly sized, non-aggressive species. They are best kept in schools of six or more to encourage natural shoaling behavior and minimize stress. These tetras primarily occupy the top levels of the tank but may occasionally explore other areas.

Suggested Tankmates

Neon Tetras (Paracheirodon innesi)
Ember Tetras (Hyphessobrycon amandae)
Harlequin Rasboras (Trigonostigma heteromorpha)
Corydoras Catfish (Corydoras spp.)
Otocinclus Catfish (Otocinclus spp.)
Rummy-Nose Tetras (Hemigrammus rhodostomus)

Suitable Plants

Including live plants in the aquarium not only enhances its natural look but also provides hiding spots and improves water quality. Here are some plants ideal for tanks housing Red Base Tetras:

Amazon Sword (Echinodorus amazonicus)
Java Fern (Microsorum pteropus)
Anubias Nana (Anubias barteri var. nana)
Hornwort (Ceratophyllum demersum)
Dwarf Water Lettuce (Pistia stratiotes)
Cryptocoryne Wendtii (Cryptocoryne wendtii)

Lifespan

The typical lifespan of Hemigrammus stictus ranges from 5 to 8 years when provided with proper care and a stress-free environment. Regular water changes and a balanced diet will help ensure a long, healthy life.

Short Description
