Well, it’s official. The corydora has died. It appears that, after a brief postmortem examination, his gills were entirely overcome by Ich; poor little guy suffocated. An interesting case, as he was plagued by a secondary bacterial infection as well (resulting in the red streaking). I wonder, in the future, how I might treat both ailments at once, as the Maracide used to treat the Ich cannot be used with other medications. In the past, I have used Coppersafe in conjunction with an antibiotic in non-planted tanks, but since Coppersafe isn’t plant-friendly, that wasn’t an option. More research is required.
