False Glass Catfish
Kryptopterus macrocephalus
A fascinating, semi-transparent schooling catfish from Southeast Asia. Unlike the more common Ghost Catfish, this species has distinct stripes or mottling along its body. They are incredibly peaceful but timid, requiring heavily planted blackwater setups with dim lighting and a large shoal to feel secure.

False Glass Catfish Care Guide Summary
The False Glass Catfish, scientifically known as Kryptopterus macrocephalus, belongs to the Catfish family group. Adults reach a maximum size of approximately 10 cm and have a compressed body shape with a moderate growth rate. Classified as peaceful, this species primarily occupies the mid-level zone of the aquarium and produces a low level of biological waste.
To thrive, the False Glass Catfish requires a freshwater only aquarium with a minimum volume of 110 litres and a tank length of at least 90 cm. Water temperature should be maintained between 22°C and 28°C, with a pH range of 5–7 and a general hardness of 1–8 dGH. A low water flow is preferred.
Due to its specialist needs, the False Glass Catfish is best suited for fishkeepers who can provide a carefully planned setup. The False Glass Catfish is typically available in one standard form.
False Glass Catfish Habitat Setup
When setting up an aquarium for the False Glass Catfish, a low water flow best suits their natural preferences. Because this species occupies the mid-level zone, the aquarium layout should prioritise open swimming space in the centre of the tank for free movement. Useful additions include leaf litter or blackwater tannins to replicate their natural soft-water habitat, dense planting to provide cover, break sightlines, and reduce stress, and floating plants to diffuse overhead light and create shaded areas.
False Glass Catfish Compatibility Notes
Classified as peaceful, the False Glass Catfish is a social species that requires the company of its own kind to thrive. When choosing tankmates, ornamental shrimp are not safe companions and boisterous or fast-moving tankmates may cause this species undue stress. Selecting tankmates that favour different water layers from the mid-level zone can help reduce competition and territorial overlap.
Who False Glass Catfish Is Actually For
False Glass Catfish is best for a fishkeeper who wants a species that can settle into a calmer community setup and can provide a keeper who can commit to a proper group of at least 5. It makes the most sense for a hobbyist who will actually build around its needs, especially plants.
The most common mistake is buying False Glass Catfish for looks first and only later discovering how its adult size, behavior, or bioload changes the whole tank plan. Another frequent problem is underestimating its social needs. A token pair or trio often behaves very differently from a real group.

False Glass Catfish Feeding & Diet Considerations
The False Glass Catfish will hunt and eat ornamental shrimp, making it unsuitable for shrimp-focused setups and will eat fry, so breeding efforts in the same tank are unlikely to succeed.

Fish Similar to False Glass Catfish
Glass Catfish
Kryptopterus vitreolus
A highly unique, completely transparent catfish from Thailand. Unlike most catfish, they are mid-water swimmers that require being kept in schools to feel secure. They are incredibly peaceful and easily outcompeted for food. They require stable water parameters and dim lighting or shaded areas provided by floating plants.
Debauwi Catfish (Three-Striped Glass Catfish)
Pareutropius buffei
A highly active, diurnal schooling catfish native to West African rivers. Unlike most bottom-dwelling catfish, they continuously swim in the mid-to-upper water column. While often sold in the trade as 'P. debauwi', virtually all specimens are actually 'P. buffei' (distinguished by having three lateral stripes instead of one). They are peaceful, require highly oxygenated water with moderate flow, and absolutely must be kept in groups.
True Julii Corydoras
Corydoras julii
A highly sought-after, peaceful schooling catfish native to the lower Amazon. They feature distinctive fine black dots on their heads (unlike the reticulated, maze-like lines of the commonly mislabeled 'False Julii', C. trilineatus) and a black-tipped dorsal fin. As obligate bottom-dwellers, they continuously sift through the substrate and strictly require soft sand to prevent erosion and infection of their delicate sensory barbels. They are highly gregarious and must be kept in groups.
Black Fin Cory
Corydoras leucomelas
A peaceful schooling catfish native to the Amazon basin, easily identified by its black dorsal fin and a dark mask-like band across its eyes. Like all Corydoras, they are bottom-dwellers that use sensitive barbels to forage. They possess a modified intestine allowing them to gulp atmospheric air, so occasional darts to the surface are normal. They are highly social and require a soft sandy substrate to prevent barbel erosion.
Indian Glassfish
Parambassis ranga
The Indian Glassfish is a fascinating schooling fish famous for its completely transparent body, allowing you to see its skeletal structure and internal organs. Originally from South Asia, they are highly adaptable but thrive best in hard, alkaline freshwater or low-end brackish setups. They are timid and must be kept in groups. Note: Artificially injected 'Painted Glassfish' suffer severely reduced immune systems and lifespans; supporting the natural, clear form is strongly recommended.
Striped Raphael Catfish
Platydoras armatulus
A highly robust, armored catfish native to the Amazon and Orinoco basins. Famous for their ability to produce audible squeaking or grunting sounds when distressed or defending territory. They are nocturnal scavengers that spend most of the day hiding in driftwood or caves. Note: Their rigid pectoral spines can easily become tangled in standard aquarium nets.
