Indawgyi stream catfish
Introduction
The Indawgyi stream catfish (Akysis prashadi) is a captivating freshwater species native to Myanmar's Lake Indawgyi region. Renowned for its peaceful demeanor and unique burrowing behavior, this catfish appeals to aquarists seeking an intriguing addition to their tanks. With proper care, it can thrive in home aquariums, offering enthusiasts a glimpse into the diverse aquatic life of Southeast Asia.
What makes the Indawgyi stream catfish unique?
Its distinctive burrowing behavior and preference for hiding in crevices set it apart from other catfish species.
Is this species suitable for beginner aquarists?
While it requires specific care conditions, attentive beginners can successfully keep this species by adhering to its care guidelines.
Care and Environment
Providing optimal care for the Indawgyi stream catfish involves replicating its natural habitat and meeting its specific needs.
What is the minimum tank size for an Indawgyi stream catfish?
A tank with base dimensions of 45 cm × 30 cm (approximately 40 liters) is sufficient for a single fish or a small group.
What are the ideal water parameters?
Maintain a temperature between 16.5–24°C, pH levels of 6.0–7.2, and water hardness ranging from 36–215 ppm.
Filtration should ensure a gentle to moderate water flow, mimicking the slow-moving streams of its natural environment. A soft, sandy substrate is essential, as the catfish often buries itself with only its eyes visible. Incorporate water-worn rocks, driftwood, and caves to provide ample hiding spots. While aquatic plants aren't typical in their native habitat, species like Microsorum or Anubias can be added for aesthetic appeal.
Feeding should consist of live or frozen foods such as bloodworms, daphnia, and brine shrimp. They may be hesitant to accept dried foods initially but can adapt over time. Offering food during the evening aligns with their nocturnal feeding habits.
Regular maintenance, including weekly water changes of 30–50%, is crucial to prevent the accumulation of organic pollutants. Ensuring high oxygen levels and clean water will promote the health and longevity of the Indawgyi stream catfish.
Are there any specific challenges in keeping this species?
They can be picky eaters and may not readily accept dried foods, requiring patience and a varied diet.
Origin and Habitat
Native to the freshwater habitats of Lake Indawgyi in Myanmar, the Indawgyi stream catfish inhabits slow-moving streams and shallow areas of the lake. These environments feature substrates of sand, gravel, and rocks, with clear to slightly turbid waters. During rainy periods, the water may become more turbid due to suspended materials. The region is rich in biodiversity, hosting over 90 fish species, including various loaches and other small fish.
What is unique about Lake Indawgyi?
It is the largest freshwater lake in Myanmar and Southeast Asia's third largest, spanning 314.67 square miles.
Temperament and Compatibility
The Indawgyi stream catfish is a peaceful, bottom-dwelling species that coexists well with other non-aggressive fish. Suitable tank mates include small rasboras, tetras, and barbs that are too large to be considered prey.
Does this species prefer to be kept in groups?
While they can be kept singly, they often exhibit more natural behaviors when housed in small groups.
Are there any fish species to avoid as tank mates?
Avoid housing them with aggressive or significantly larger fish that may view them as prey.
Interesting Facts
The Indawgyi stream catfish is known for its burrowing behavior, often burying itself in the substrate with only its eyes protruding. This behavior provides both camouflage and protection from potential predators.
In the wild, males construct nests where females lay eggs, showcasing a unique reproductive strategy among catfish.
Despite their peaceful nature, they are nocturnal predators, feeding on small aquatic crustaceans, worms, and insect larvae.
How long can the Indawgyi stream catfish live?
With proper care, they can live between 5–8 years.
