These 3 Anthias have been in QT for 12 days. One anthias developed a small pin prick red spot yesterday evening. Thought it might have been from fighting because the two bigger anthias occasionally spar. This morning another anthias looked like it has a white patch on side and the one with red spot looks like there may be a little white around it. I dosed metroplex and kanaplex. Am I the right track? Is there anything else I should be dosing? I also have hydroplex, prazipro and Cuppramine. The fish were dipped in hydroplex before entering my QT and are from Divers Den so have had a round of copper before arrival. Ammonia badge is yellow. 8g water change on 20g QT e/o day. 0 nitrite 5-10 nitrate. Thanks for the help!
