thanks, I dont have any of that medication on hand, but I do have a frag tank I can move her to. Would that be best or just a water change in her qt?If nobody else is still awake to give alternate advice... I would remove her from the prazi and give her a bath in methelyne blue if you have any, it has saved my blue tang a few times now (completly different scenario but MB is listed as a first response besides the salvage protocol I shared) https://www.reef2reef.com/threads/methylene-blue.257467/
