I have a inch sized baby hippo tang in my 50 gal (yes I am very aware that its considered taboo to keep tangs in small sized tanks, but as I mentioned she is barley an inch and I plan on upgrading within a year or so, long before she will outgrow the tank). She has some odd spots on her than I cant quite make out and wanted to see if anyone has a opinion on what they might be and if they are dangerous. Near her fin there's a spot and her back third portion of the body is a dark blue in contrast to the rest of her body. And near the top back portion there are something that looks like whiteish streaks. No irregular movement (from my somewhat limited knowledge) swims happily with her clown fish friends.
