I have a frogspawn that was doing great in my tank. nothing has changed but the last few weeks it has been closed up. I started to notice some littel brown spots on the ends of some of the tentacles. over the last few days it has gotten more noticable and severe. The heads are still closed. I'll try to get some pics of it later tonight. I was thinking i might want to try a freshwater dip. How long should I dip it for? I also read somethign aobut an iodine solution? How much iodine/per parts of freshwater? saltwater? Any help would be appreciated. Thanks
