[ARRIVED 8-OCT-2025] SUPER RARE: Corydoras Hastatus - The Dwarf Sedge Cory 1-2cm

Description

The Tiny Cory That Breaks All the Rules!

Short Description:
Meet Corydoras hastatus, the extraordinary dwarf cory that shatters expectations! Unlike its bottom-dwelling cousins, this miniature marvel spends most of its time swimming in mid-water schools, creating a dazzling display of synchronized movement. A perfect choice for nano tanks and peaceful community aquariums.


Key Features & Highlights

  • 🌊 MID-WATER SCHOOLING BEHAVIOR:** Watch in amazement as these corydoras school actively in the open water, unlike traditional bottom-dwelling species. Their synchronized swimming is mesmerizing.

  • šŸ”Ā TRUE DWARF SIZE:** Reaching just over 1 inch (2.5-3 cm), they are one of the smallest corydoras species, making them perfect for nano aquariums as small as 10 gallons.

  • šŸŽØĀ SUBTLY STUNNING PATTERN:** A sleek silver body adorned with a horizontal black line and a distinctive black spot at the base of the tail, creating an elegant and sophisticated appearance.

  • ā˜®ļøĀ PEACEFUL NANO COMMUNITY FISH:** Completely harmless and ideal for tanks with other small, peaceful species like microrasboras, small tetras, and shrimp.

  • šŸ‘ļøĀ FASCINATING TO OBSERVE:** Their unique behavior—alternating between mid-water schooling and brief bottom foraging—provides endless entertainment.


Detailed Description

Discover the captivating world of Corydoras hastatus, the dwarf cory that defies convention. Often called the "Micro Swordtail Cory" due to its shape, this species offers a completely different experience from typical corydoras. Their high-energy, schooling nature in the water column makes them a dynamic and engaging addition to any peaceful aquarium.

While they will occasionally dart down to the substrate to forage like their larger relatives, their primary domain is the open water. A shoal of these tiny fish moving as one unified group is a breathtaking sight that brings a new dimension of activity to the middle levels of your tank. Their small size and minimal bioload make them an excellent choice for beautifully planted nano aquariums where every inch of space counts.

Ideal For:

  • Nano Aquariums (10+ gallons)

  • Heavily Planted Tanks

  • Peaceful Community Setups

  • Shrimp Tanks

  • Aquarists seeking unique behavior
