OK here goes ... I'm stuck at work on christmas eve I have made a tank for my little girl i plan to give her tomorrow. I have 4 danios 2 cory's and life plants. both cory's show velvet only one has become lethargic so i got some medication (hard to find something that doesnt have copper and is ok for scaleless fish ! finally settled on Maracide it says its for ich velvet and other external parasites. I am to put the medication in on day 1, 3 and 5 . It is now day 3 i will put more in tonight but the one that is listless just sits at the bottom and does nothing but breathe heavy . only will move if i actually touch him. is there a good chance that he will pull through? in which case i will still give him to my daughter but if he won't I would rather just not go thought the "dad got me a sick/dead fish for xmas" thing. by the way did a water tests before I put in meds and it was within normal cycled tank range.
