Orange Venezuelan Cory (Pack of 4) Live Fish
The Orange Venezuelan Cory is a peaceful schooling fish compatible with most nano aquarium residents, including dwarf cichlids and angelfish.

Buying Guide
Key considerations when choosing Corydoras for your tank:
- Tank size and stocking: Corydoras are peaceful, social fish. Plan for groups of at least 4-6 individuals for most species to reduce stress and promote natural schooling behavior.
- Substrate: Use sand or very smooth gravel. Sharp or coarse substrates can injure barbels and undersides during foraging.
- Water conditions: Maintain stable tropical freshwater parameters. Sudden changes can stress Corydoras and disrupt feeding behavior.
- Food: They accept dry, frozen, and live foods. Providing a varied diet supports health and coloration without overfeeding.
- Tank mates: Choose peaceful species that won’t outcompete them for food or harass the group.
- Appearance and variety: Orange varieties provide bright color accents, while Panda and Black variants contribute contrast and texture to the aquascape.
