Recently bought some ferns online. This trident java fern has some black dots on it. Not sure what it is, though I forget where I've seen it before (must have been years ago). I'm hoping someone can tell me what it is and what should be done. I tried a potassium permanganate dip for 20 minutes, but have yet to add it to my tanks as it's weird...
