The title says it all. All of my zoos, 8 different colors and hundreds of them are not opening. I had some weird snail/nudi looking things all over them when I came back from a cruise. shrooms and all brains still look great, water parameters are perfect, I tried doing a partial water change, what else can I do? Do I need to try a freshwater dip? If so, how long should I dip, and is it safe to do my live rock and my trachyphillia and favites brains and shrooms? I must admit I'm a little paranoid about doing the fresh water dip, but I understand that it will also kill flat worms, and i got some of those too. Is there an additive that would be better? thanks for all you help.
