The scientific name Hyalobagrus ornatus refers to the Ornate Glass Bagrid, a representative of the family Bagridae. This catfish originates from Southeast Asia. It can be found in the river systems of the southern part of the Malay Peninsula, as well as on the island of Borneo (Kalimantan). Its natural habitat consists of peat rivers and other bodies of water characterized by a high concentration of tannins.

Description
This tiny fish, reaching a length of only up to 3 cm, stands out for its activity, which is reflected in its appearance. It has a slender body and well-developed fins, ensuring fast movement. The head is quite large, equipped with big eyes that help it perceive even dim light in murky waters. Orientation and food search are also facilitated by sensitive barbels located around the mouth. The body coloration is silvery, and the belly area is semi-transparent. The pattern includes a black stripe running along the entire length of the body and dark speckles.
Habitat
The species inhabits waters of Southeast Asia, including the Muar River basin on the Malay Peninsula and the Kapuas River basin on the island of Borneo. In nature, these fish inhabit peat swamps and slow-flowing streams. The water in such biotopes is usually characterized by softness and an acidic pH, which is important to consider when creating conditions in captivity.
Behavior and Compatibility
This peaceful and active fish species prefers to be in a group of its own kind. To maintain their comfortable existence, it is recommended to form schools of 8–10 individuals. The Ornate Glass Bagrid coexists perfectly with most other aquarium inhabitants if they are similar in size and temperament.
Care and Maintenance
For a school of 5–6 fish, the optimal aquarium volume starts from 50 L. The use of dark substrate and the placement of several areas with dense aquatic vegetation are welcome in the design. Under low light conditions, these catfish show the greatest activity. When the light is on during the day, they will seek shelter, so it is important to provide hiding places for them. Keeping these fish is not very difficult. They need soft, slightly acidic water and a relatively cool temperature for tropical species — no higher than 25°C. Standard aquarium maintenance includes weekly partial water changes with fresh water, cleaning organic waste, and keeping equipment in working order. It is important to note that the Ornate Glass Bagrid is sensitive to strong currents that can be created by the filtration system. When choosing a filter, preference should be given to models that provide gentle filtration and do not create excessive water movement. This species is omnivorous. It accepts most popular foods of appropriate size, whether dry (flakes, granules), frozen, or live/fresh, such as Artemia, bloodworms, Daphnia, and so on.
Diet
Being an omnivorous species, these fish easily adapt to a varied diet. They accept most common foods of appropriate size — both dry (flakes, granules) and frozen or live/fresh, including Artemia, bloodworms, Daphnia, and so on.

How to choose
When purchasing, select active individuals with clean fins and no visible skin damage. Given the rarity of the species in aquaristics and its endangered status, it is important to ensure the fish's health, as adaptation to new conditions can be difficult. It is recommended to observe the behavior of individuals in the store: healthy fish show interest in food and do not show signs of emaciation.
Frequently asked questions
The essentials: size, tank volume, water parameters and care
How big does Ornate Glass Bagrid get?
An adult reaches 3 cm in length. Plan the tank around the maximum size: the fish quickly outgrows a cramped setup.
What size aquarium does Ornate Glass Bagrid need?
The minimum recommended volume is 40 L. A smaller tank speeds up nitrate build-up and raises stress levels.
What water parameters does Ornate Glass Bagrid need?
Temperature 21–25 °C, pH 6.6–7.2, hardness 5–18 dGH. Stability matters more than exact values: sudden swings are harder on the fish than a small deviation from the ideal.
How long does Ornate Glass Bagrid live?
Around 4 years when kept properly. Lifespan depends directly on tank volume, water quality and a varied diet.
Is Ornate Glass Bagrid aggressive?
Temperament: peaceful (regular). Keep this in mind when choosing tank mates.
How many Ornate Glass Bagrid should be kept together?
Recommended setup: small group (5–6 individuals). Ignoring this is a common cause of stress and disease.
What does Ornate Glass Bagrid eat?
Diet type: sinking (any). Feed small portions that are finished within a couple of minutes — overfeeding does more harm than underfeeding.
What is the scientific name of Ornate Glass Bagrid?
The scientific name of the species is Hyalobagrus ornatus, family Bagridae. It also appears in the literature as: Pelteobagrus ornatus, Pseudobagrus ornatus.
