How long do Julii Corydoras live?
Julii Corydoras live 5 or more years with good care. Stable, mature water and a soft substrate support a long life.
What do Julii Corydoras eat?
Feed sinking pellets, wafers, and frozen/live foods like bloodworms and daphnia. The common error is assuming they live on leftovers; give them dedicated bottom food.
Tank size and water parameters
A 15-20 gallon (57-75 L) tank suits a group of 6. Target 72-79°F (22-26°C), pH 6.0-7.5, soft to moderate water, zero ammonia and nitrite, nitrate under 20 ppm. Keep in groups of 6+ on smooth sand.
Common mistakes with Julii Corydoras
Usual errors: sharp substrate damaging barbels; scrap-only feeding; too small a group; and confusing them with leopard corys at purchase, which is harmless but worth knowing.
Beginner mistakes to avoid
- Sharp gravel — use sand or smooth substrate for barbel health.
- Feeding only scraps — give them their own sinking food.
- Keeping a lone cory — they need a school of 6+.
- Poor water quality — sensitive to ammonia and nitrite.
