Just went in to check on my 55 gallon tank before bed, and there’s a half eaten tetra on the substrate. I watched the tank for a long time today and yesterday, and nothing really looked off, except one tetra acting a little more skittish than the others. I did my second dose of Levamisole for the roundworms today. Is it likely he died and then was eaten, or do you think it was the acara? I am now down to 10 bloodfins. All the other fish are just acting like they usually do after lights out, except the acara looks like a little evil lol. I did a treatment of levamisole two weeks ago, did a second one today, and planned to do a third next week, just to be cautious. I don’t want him eating more of the tetras, Can I just take them to my LFS like day after tomorrow or something? How important is that third treatment?
