Corydoras loretoensis  Nijssen & Isbrücker, 1986


imilar to C. armatus, but this species is higher bodied. There is also a variety with an eye mask which may be the juvenile pattern of C. loretoensis, with this trait disappearing as they grow into adulthood.

Corydoras loretoensis

 

At first glance in your LFS you would be challenged to think of a more unspectacular looking cory, but believe me when you get them home and settled in your aquarium you will be surprised at the beauty of this little catfish. Of course not a looker in the sense of colouration, but the high dorsal with the black edging and the black spots on the grey body coupled with its gregarious behavior will make it a firm favourite in your fish room/hut. I picked mine up at an auction and wondered why I had bid for them, but I am very glad that I did as I had not kept this Corydoras in over 30 years of fishkeeping and it sparked a bit of exhilaration in my Fishhouse.

The head view image above shows the unusually large eyes which are situated high on the head. The snout is very short and angular.

 

Conclusion: This is a very social Corydoras and one that you should consider if you have not kept this species before.

 

 

 

Characteristics
Head short and blunt. Eyes large which are situated high on the head. Dorsal fin elongated.

Colour

Ground colour of head and body grey with black spots and blotches. Dorsal fin spine is black and the rest of the fin may have a few dark spots/blotches. Rest of fins hyaline but some specimens may show faint bars in the caudal fin. There is a hint of a pale eye mask in adults.

 

Compatibility
This is akin to most of this genus, very peaceful, and would be best housed with small to medium sized tankmates such as Tetras, Rasboras and Danios or in a species tank for breeding purposes. Best to purchase 6 individuals or more as they will be happier in a group.

Breeding

As per Corydoras 'T' mating fashion but not one of the easiest members of this genera to spawn but once you have been successful they should spawn at regular intervals. Will lay their eggs in Java moss, spawning mops or the corners of the tank glass. There have been reports (Fuller 2013) of this species laying eggs in the sand substrate.


Sexual differences

Males tend to be more brightly coloured with the females showing a paler colouration.

 

Diet

Readily accepts a mixed and varied diet which includes granular foods, tablet food, frozen bloodworm and good quality flake to name but a few.


Etymology

Corydoras: Cory = helmeted; doras = leathery skin,(helmeted Doras) cuirass.
loretoensis:
From Loreto, a department in Peru where this Corydoras species was found.
