How long have you had the tank running?
How long have you had the julii?

*Also depending on the type of pleco you have he may get quite large.

The tank is 4 months old, and the cory is about 5 weeks old. Thanks.

Seems like he may have nitrate poisoning. As julii's can be a very sensitive corydora. However 20ppm nitrate is not all that high, but maybe it was a spike, that could have caused it.

i've had experience with cories and have lost some to the same symptoms you have listed. Unfortunatly I have not been able to diagnose what it is. Cories can be very sensitive to their environment but 20 ppm of Nitrate isn't that high. I don't think its nitrate poisening. We aren't supposed to just guess at what to treat them with but personally I would try an antibiotic treament.

Thank you both. Unfortunately, before I could do anything, he died. I will try again, but be more mindful of the nitrates.
