Hello, my newest batch of neons and rummies has ick, I've read they're sensitive so does anyone have a fav ick med they've used successfully on neons and otos ? No heat or salt, just looking for safe meds. Tank has plants and snails though i can remove them if its not plant safe. Thank you! Rummies seem ok in the polyguard I had on hand but I'm weary of treating a whole tank of neons with something.
