Hi I'm new to this site and to having fish. My previous fish had ich, I treated with raising water temperature & salt water treatment - unfortunately, all my fish & shrimp died . So I waited a couple weeks, got new fish & shrimp .... and the night after I brought my fish home, it appeared as though my male platy has ich, agh! How can I treat without killing everything again?? Any advice would be great! Also, I am hoping to get a smaller tank tomorrow to use as a qt. & one of my platies is pregnant & I saw a couple fries today ... will treating ich harm her & the fry (provided they don't get eaten)?
