Kaste Posted December 2, 2020 Share Posted December 2, 2020 I found one of my Panda Cory's dead this morning, Had a red blotch or injury on his left side. Seemed fine yesterday. I check tank daily since I have had a few other Cory issues. Not sure if I should do a preventative dose of meds or if this was an injury. I have lost 3 Panda's from this shipment. One arrived dead, one died of fungus and now this - red blotch death. Tank parameters are all great. Water change on every Friday. 55gal tank. Tank mates: 6 honey gourami, 9 Harlequin Rasboro, 7 molly, 2 mystery snail, and 4 (-1 now) Panda Cory. I did the trio in QT, did Paracleanse on week3 and did Maracyne and IckX when fungus happened. All other fish seem ok. 4 Link to comment Share on other sites More sharing options...
Colu Posted December 3, 2020 Share Posted December 3, 2020 It look to be red blotch disease very common in corydoras it can be treated with API melafix Link to comment Share on other sites More sharing options...
Colu Posted December 3, 2020 Share Posted December 3, 2020 It is usually combination of stress and poor water conditions Link to comment Share on other sites More sharing options...
Kaste Posted December 3, 2020 Author Share Posted December 3, 2020 Do you think I should treat the whole tank,? Is this contagious to the other fish? I listed tank mates above, or should I wait to see if I get anymore with the same symptoms. The water conditions are all good. I am checking every few days and do approx. 30% water change on Fridays. 67 years old and all this is new. learning by what seems to be lots of mistakes. 😕 again, thanks so much.

Colu Posted December 3, 2020 Share Posted December 3, 2020 It is a common disease of corydoras some people think it to do with toxic secretion corydoras release when stressed during neting and transporting I would do a treatment of API melafix as a precaution Link to comment Share on other sites More sharing options...
