Hello. I have an Exquisite fairy wrasse that I got from LiveAquaria back in September. He went through a QT, observation only, then went into the main tank a few weeks ago. He did fine in QT, he ate well and looked good. Since being in the main tank, he's gotten very skinny and his color has faded. He eats very well, he's always right in the mix getting his share of the food. The fish normally stays in the top portions of the tank, sometimes it seems he's blown around a bit by the flow. Any ideas what I should treat, if I can catch him. I've thought a freshwater dip to see about flukes, and I've thought about maybe internal parasites. I have Metroplex, General Cure, Prazipro, as well as several other medications on hand. Any help would be appreciated. Thanks.
