Cat-eLog Data Sheet
Scientific Name	**Corydoras trilineatus** Cope, 1872
Common Name(s)	Leopard Cory
Type Locality	Tributary of Río Ambyiacu, Peru.
Synonym(s)	Corydoras dubius, Corydoras episcopi
Pronunciation	Kory DOOR ass - try lin knee ah tuss
Etymology	Cory = helmet, doras = skin. In this case it was incorrectly used to mean armour (cuirasse) instead of skin in allusion to the dual rows of plates that run along the flanks of this genus. From the Latin Tres meaning three and lineatus meaning 'of a line'. Alludes to the two pale and single black line running along the fishes body.
Species Information
Size	55mm (2.2") SL. Find near, nearer or same sized spp.
Identification	Corydoras are identified by their twin rows of armour plates along the flanks and by having fewer than 10 dorsal fin rays. They are most commonly confused with the other genera in the sub-family, namely Brochis, Scleromystax and Aspidoras. Probably the most misidentified fish commonly found in aquatic retailers who incorrectly sell it as C. julii. The true C. julii is such a rare import that sheer numbers mean you are unlikely to really encounter this Brazilian fish. C. julii is similar to the more spotted forms of C. trilineatus but has no trace of any reticulated colour patterning at all and is entirely covered with small, distinct spots. It's mid-lateral black stripe is fainter and does not reach as far towards the fishes head as in C. trilineatus
Sexing	Females grow larger and are more full-bodied, this is best observed from above the fish. Males will typically have more pointed as opposed to more rounded fin tips as they mature.
Habitat Information
Distribution	Peruvian amazon: Rio Ampiyacu, Rio Ucayali and the Yarina Cocha. Ecuador: Rio Pastaza.

pH	5.8 - 7.2
Temperature	16.0-25.0°C or 60.8-77°F (Show others within this range)
Other Parameters	A hardy species that will tolerate most water conditions found within a reasonably maintained aquarium.
Husbandry Information
Feeding	Sinking pellets and frozen bloodworm are ideal although all prepared foods that reach the bottom are accepted.
Furniture	Sandy or small rounded gravel is required to ensure the fishes barbels are not damaged in the search for food. Some plants should be used to provide shade and a sense of security.
Compatibility	This commonly encountered Corydoras is a perfect community tank citizen.
Suggested Tankmates	Should be kept in a shoal of at least six individuals. This, along with the presence of some mid water shoaling species, will increase the confidence of the fish in a community tank environment.
Breeding	The fish appears to prefer clean, soft water and should be conditioned in such an environment. pH and temperature seem less important but a drop in temperature may induce spawning. The eggs hatch after four to five days. The eggs are very susceptible to fungus and best removed, treated and the fry allow to hatch in a very controlled environment. The young can be raised on newly hatched brineshrimp again vigilance in respect of water quality is paramount.

Corydoras trilineatus Cope, 1872

Common Name(s)

Leopard Cory

Type Locality

Tributary of Río Ambyiacu, Peru.

Synonym(s)

Corydoras dubius, Corydoras episcopi

Pronunciation

Kory DOOR ass - try lin knee ah tuss

Etymology

Cory = helmet, doras = skin. In this case it was incorrectly used to mean armour (cuirasse) instead of skin in allusion to the dual rows of plates that run along the flanks of this genus. From the Latin Tres meaning three and lineatus meaning 'of a line'. Alludes to the two pale and single black line running along the fishes body.

Species Information

Size

55mm (2.2") SL. Find near, nearer or same sized spp.

Identification

Corydoras are identified by their twin rows of armour plates along the flanks and by having fewer than 10 dorsal fin rays. They are most commonly confused with the other genera in the sub-family, namely Brochis, Scleromystax and Aspidoras.

Probably the most misidentified fish commonly found in aquatic retailers who incorrectly sell it as C. julii.

Temperature

Other Parameters

A hardy species that will tolerate most water conditions found within a reasonably maintained aquarium.

Husbandry Information

Feeding

Sinking pellets and frozen bloodworm are ideal although all prepared foods that reach the bottom are accepted.

Furniture

Sandy or small rounded gravel is required to ensure the fishes barbels are not damaged in the search for food. Some plants should be used to provide shade and a sense of security.

Compatibility

This commonly encountered Corydoras is a perfect community tank citizen.

Suggested Tankmates

Should be kept in a shoal of at least six individuals. This, along with the presence of some mid water shoaling species, will increase the confidence of the fish in a community tank environment.

Breeding

The fish appears to prefer clean, soft water and should be conditioned in such an environment. pH and temperature seem less important but a drop in temperature may induce spawning. The eggs hatch after four to five days. The eggs are very susceptible to fungus and best removed, treated and the fry allow to hatch in a very controlled environment. The young can be raised on newly hatched brineshrimp again vigilance in respect of water quality is paramount.
