Yesterday the fish were fine. Noticed a very small cut on the catfish gills and today, this. Water tests are good. Nothing new added to the tank. Has been set up over 3 years. Any ideas? 
catfish and bichir very bad off.

Also, the ornate bichir has died and at last check the catfish was on its side a very labored breathing. Only other fish in tank is a 3" female convict, unaffected.
When I saw it, that was my first guess. Here is a pic of the water test. Left to right, nitrite, ammonia, nitrate. All good.
About the only thing I can find that comes close to my issue is a herpes virus found in catfish. It can lay dormant for years and then kill in 24 to 48 hrs. Both the catfish and bichir are now dead and the convict is still unaffected. I looked at the gills of the bichir and there was almost nothing to be found but was not tore up like the catfish. I don't know, but I guess I'll be researching the best way to sterilize my tank now.
