JULII CORY (Corydoras Julii)

Julii Cory (Corydoras julii) Care Guide

Basic Information

️ Tank Requirements

️ Diet

Julii Corys are omnivores and bottom feeders, but they still need direct feeding — they can’t live on scraps alone.

Feed:

• Sinking catfish pellets or wafers

• Frozen or live bloodworms, daphnia, brine shrimp

• Blanched vegetables (e.g., zucchini)

• Occasional algae wafers or spirulina tablets

Feed once or twice daily. Remove uneaten food to avoid water quality issues.

Behavior & Tank Mates

• Schooling fish — should be kept in groups of 6 or more

• Very peaceful, shy if alone

• Active, playful, and safe for any peaceful community setup

Compatible Tank Mates:

• Tetras (neon, ember, cardinal)

• Rasboras

• Guppies, mollies

• Dwarf gouramis

• Other peaceful bottom dwellers (e.g., other Corydoras, otos)

• Shrimp and snails

Avoid:

• Aggressive or large predatory fish

• Fish that may outcompete them for food at the bottom

Breeding

Julii Corys can be bred in home aquariums with proper conditions.

• Trigger spawning with cooler water changes

• Use soft, clean water

• Males chase the female; she lays sticky eggs on glass or plants

• Remove adults after spawning to prevent egg eating

• Eggs hatch in 3–5 days, and fry can eat baby brine shrimp or powdered fry food

Maintenance Tips

• Keep substrate clean to avoid barbel erosion or infections

• Perform weekly water changes (25–50%)

• Avoid sharp gravel

• Provide low to moderate flow to mimic river environments

⚖️ Pros & Cons

Note on Mislabeling:

Many “Julii Corys” in stores are actually Corydoras trilineatus (Three-Line Cory), which look similar. True C. julii have distinct, spotted patterns, not reticulated lines.

✅ Ideal For:

• Community tanks

• Beginners and experienced hobbyists alike

• Peaceful planted aquariums

• Aquarists wanting social, active bottom dwellers
