Smudge Spot Cory (Corydoras Similis)
The Smudge Spot Cory, also known as the Similis Corydoras, and Violet Cory Catfish, is a rare but captivating species in the aquarium trade. They are known for their distinctive dark violet hue in their mature form, making them a standout addition to nano, community, and planted aquariums. The Smudge Spot Cory boasts a cream-colored base with intricate brown spots adorning their heads. These spots cascade down their bodies in precise rows above the lateral line, gradually diminishing in size towards the caudal peduncle. A tan-colored region beneath the lateral line provides a striking contrast, while a captivating blue blotch emerges behind the dorsal fin base, culminating at the caudal peduncle. This ethereal blue intensifies as it progresses toward the caudal peduncle, creating a visual spectacle. The ventral surface boasts a pristine whitish-cream tone, while the fins maintain a translucent quality. They can reach an adult size of up to 2.5 inches.
This peaceful shoaling fish thrives best when housed in groups of no less than 6 individuals, creating a dynamic and harmonious aquarium environment. The Smudge Spot Cory is compatible with a wide array of popular fish species, including Dwarf Cichlids, Tetras, small to medium-sized Barbs, Gouramis, and other peaceful Catfish. Avoid housing them with aggressive, territorial, or larger fish that might see them as food or compete with them for food at the bottom of the tank.
In terms of diet, the Smudge Spot Cory is omnivorous and easy to feed. They will eat most food that sinks to the bottom of the tank, including sinking pellets, flake food, and other sinking foods like catfish pellets. They also have a carnivorous side, enjoying foods such as bloodworms, brine shrimp, and daphnia.
In terms of habitat, the Smudge Spot Cory thrives in an environment that mirrors its native Amazon habitat. A sandy or smooth gravel substrate, complemented by carefully arranged driftwood branches and intermittent dried leaf litter, will contribute to the authenticity of this beautiful setting. While aquatic plants are absent from their natural habitats, you can imbue the water with a rich brown hue by allowing the wood and leaves to impart their tannins. Regularly removing decaying leaves and replacing them will help maintain optimal water quality. Alternatively, the Smudge Spot Cory will also flourish in a well-planted aquarium.
Regarding their water parameters and aquarium size, the minimum recommended aquarium size is 20 gallons for a school of 6 Smudge Spot Cory. They prefer water parameters with a pH range of 6.0-7.5, a hardness of 2-12 dGH, and a temperature range of 72-79°F (22-26°C). Regular water changes, coupled with a mindful approach to feeding, will ensure the long-term well-being of these undemanding and resilient fish.
