I agree with Dragon and Sunlight. I have 4 emerald corys myself in a 10g planted tank and even with the four of them they are still VERY shy and get scared easily. One cory is not going to be happy alone, and in a 3g tank you are really pushing the bioload with just the 2 fish in there. If you are doing only a 40% change every 2 weeks your fish ARE eventually going to get sick. You definitely need at least two 50% water changes EVERY week.

If you don't want ghost shrimp, which in my experience die very easily, you could try Amano shrimp. I believe their life expectancy is only about a year though, and all shrimp are greatly affected by bad water quality and can die within hours.

Also, don't know if it was mentioned but did you remove the metal wire that is inside the leaf hammock? Someone told me to do so with mine to prevent it from rusting.

I am sorry to say ALL Cories NEED a SCHOOL.
