Corydoras sodalis (incorrect as agassizii).

30. November 2022

There are four species of beautiful corydoras, which are practically without exception available as wild collected specimens from Brazil, because even experienced breeders have a hard time with them. In addition, these species occur in masses and can therefore be offered in large numbers and very cheaply, so there is little incentive to breed them. After all, sustainable natural harvests make more ecological sense than captive breeding and provide local people with an environmentally sound, secure income.

These four species we are talking about here are Corydoras agassizii, C. ambiacus, C. schwartzi and C. sodalis. Unfortunately, they are repeatedly given wrong names. A portrait of Cordoras schwartzi can be found here: https://www.aquariumglaser.de/en/fish-archives/corydoras-schwartzi-2/

This post is about Corydoras sodalis. For reasons that go back to a mistake in the 1960s, this actually hardly to be confused armored catfish is traded again and again as C. agassizii. This is especially difficult to eradicate, because C. sodalis and the “real” agassizii often occur together and are therefore often imported mixed. C. agassizii on the other hand is – also wrongly – mostly called C. punctatus, as well as C. ambiacus, which is furthermore difficult to distinguish from C. agassizii. A real name drama!

Concerning care there is not much to say about C. sodalis, the fish will do practically everything, if you fulfill the basic requirements of Corydoras: no sharp-edged substrate, preferably soft river sand, low-germ water and specific feeding. Corydoras are not scavengers! The water temperature should be between 22 and 28°C, pH and hardness are irrelevant.

The reason why these catfishes evade breeding lies in their natural history. The mass occurrences are most likely nothing more than spawning migrations that take the fish to small, shady tributary streams where they spawn. In the aquarium, they spawn only at night, in complete darkness. And because they are strong spawn predators, there is nothing left of the egg splendor the next morning.

Corydoras sodalis Colombia

22. April 2022

Widespread species often show coloration differences in the different parts of the distribution area. So also the beautiful Corydoras sodalis, which is reported from Peru, Brazil and Colombia. From Colombia we could now import C. sodalis, which differ quite clearly in color and figure from e.g. animals imported from Brazil (see https://www.aquariumglaser.de/en/fish-archives/corydoras-sodalis-2/).

Corydoras sodalis

3. April 2017

We received beautiful coloured Netted Corys. The species Corydoras sodalis is quite often imported, but mostly under the completely wrong name of Corydoras punctatus. The real C. punctatus originates from Surinam, occurs hardly ever in the trade and looks very similar to the well known species C. julii and C. trilineatus. A cory that can be really easily confused with C. sodalis is C. reticulatus. Both have the same pattern and the same body shape, but in C. reticulatus always a clearly marked, dark spot is present in the dorsal fin, which always lacks in C. sodalis.

The extraordinary nice colours in our recently imported C. sodalis can possibly be due to the breeding season of the species. The closely related C. pantanalensis (formerly known as C5) also shows a very nice pattern during the breeding season. However, C. sodalis reaches onyl a maximum length of about 5-6 cm, while his cousin from the Pantanal becomes much larger. The natural distribution of C. sodalis is a large area in the upper Amazon region of Peru and Brazil. Our current import originates from Brazil.
