Ah, the Corydoras paleatus ! This little freshwater catfish fascinates aquarists the world over. As a keen aquarist, I've had the chance to observe these charming creatures up close. Let me tell you everything you need to know about this little aquatic jewel from South America.
Discovery and characteristics of Corydoras paleatus
A catfish with distant origins
In fact, it was the famous Charles Darwin who discovered this fish during his travels in the 1830s. What a story! The Corydoras paleatus is native to the fresh waters of South America, more specifically Uruguay, Paraguay, Argentina and southern Brazil. It is found in a variety of habitats: rivers, tributaries, ponds and small streams.
An endearing physique
This small fish measures between 5 and 8 cm in length. Its grey body is dotted with black spots and mottles, giving it a truly unique appearance. I've even seen some albino specimens - a real feast for the eyes! What has always fascinated me about the Corydoras paleatusThese are the sensitive barbels around the mouth. These "whiskers" enable it to search the ground for food.
A long-term companion
Did you know that these little guys can live up to 12 years in an aquarium? That's quite a lifespan for a fish of this size! With proper care, you can expect to enjoy their presence for 6 to 12 years. It's quite a commitment, but believe me, it's worth it!
Maintenance and care of Corydoras paleatus in the aquarium
The right habitat for happy fish
So that your Corydoras paleatus the right environment. Here are the ideal parameters:
- Minimum volume: 100-120 litres
- Front length: 80 cm minimum
- Temperature: 18-26°C (ideally 20-24°C)
- pH: 5.5-7.5
- Hardness: 1-15°dGH
Don't forget that these fish love to live in groups! I always recommend having at least 6, but ideally 12 or more. They're so much happier in a group!
A varied diet for healthy fish
Le Corydoras paleatus is omnivorous, which makes feeding easier. In my aquarium, I offer them a varied menu:
| Type of food | Frequency |
|---|---|
| Granules for groundfish | Daily |
| Worms (tubifex, bloodworms) | 2-3 times a week |
| Crustaceans (artemia, daphnia) | 1-2 times a week |
| Plants (blanched spinach, courgette) | Once a week |
This variety will keep your little aquatic companions healthy and brightly coloured.
Cohabitation and behaviour
Le Corydoras paleatus is a peaceful and calm fish, which makes it an excellent roommate for other peaceful species. I've always been impressed by their ability to get along with almost any non-aggressive freshwater fish. They get on particularly well with blue neoncreating a striking contrast in the aquarium.
Fun fact: these little guys can produce sounds by lifting their pectoral fins. The first time I heard this "click-click", I thought there was something wrong with my filter! But no, it was just my Corydoras chatting to each other.
Reproduction and characteristics of Corydoras paleatus
The reproduction of Corydoras paleatus is a fascinating spectacle. These fish are oviparous, which means that the female lays eggs that are then fertilised by the male. To encourage egg-laying, I have learnt to simulate natural conditions by slightly lowering the water temperature and increasing the amount of food.
Sexual dimorphism is quite marked in this species: the females are generally larger and rounder than the males. This is a detail that has always helped me to balance my breeding groups.
Once the eggs have been laid, incubation lasts between 4 and 6 days. It's always a thrill to wait for the little Corydoras to hatch!
Contrary to popular belief, the Corydoras paleatus is not a "cleaning fish". They will scour the substrate for food, but they are no substitute for good aquarium maintenance. In fact, if you're looking for a real cleaner fish, I'd recommend theAncistrusAn excellent companion for keeping your aquarium clean.
