Corydoras Problem

I'm new to fish keeping so please forgive me if some of my questions have obvious answers. I have a cycled twenty gallon tank stocked with three assorted cories (Schwartz, emerald, and an unknown) and six danios. I started of with three emeralds. two of them died for unknown reasons and were replaced with the Schwartz and the unknown. The lone emerald hides most of the time so I don't see him very often but when I caught I glimpse of him recetnly I noticed that his whiskers were gone! I don't know how this happened. The substrate is not abrasive and I feed him Omega One shrimp pellets supplemented with fallen fish flakes. I was thinking that it might have something to do with fungus? All advice and help is welcome.

It could be because of a number of causes, such as poor nutrition, Bacterial infection, or maybe even some nipping going on. In my advice, I would put it somewhere else and nurse it back to health, either in a breeder net or in a quarantine.

I don't have a quarantine tank or a breeder net. What is a breeder net?

A breeder net is a net that sits in the tank that is used to separate fish inside a tank.

Cories are susceptible to nitrogen waste and this is one of the main causes of the barbels to be damaged. You should test your water for ammonia/Nitrite/Nitrate. If you dont have test kits, you should do 50% water changes every week for a couple months and cut back on feeding. Personally, I think sand is the only substrate they should be kept in as the sift through the sand. I have had barbel damage even with rounded gravel.

Cories can be very timid if they are not with similar patterned Cories. It take around 5 for them to be comfortable.

If you would like to post a pic of the third cory, I can ID it for you.

How long has your tank been running? It may not be cycled, it can take 2 months to cycle.

Consider the needs of your fish before acting on your desires.

It has been running since early September. I'll do a water test when I get back from school. I have the Mater Test Kit with the liquid bottles. Thanks for all your help.

The Ammonia was 0 or very very little. (Hard to tell between yellow and light green) The nitrite was 0.

Ammonia and nitrite are great for determining if the tank is established. Do you have a nitrate test? Nitrate tests can be used to see how we'll the tank has been cleaned.

I recently did a nitrate test and it read .5 ppm.

I am fascinated by the concept of a "breeder net". I have always heard that cories have to be handled very carefully when using nets. Are they really okay in these "nets"? I have always used those hard plastic breeder boxes for injured or dying fish, but the net seems like a much better idea. Can you tell us more?
