I have a 125 tank . It’s been running for 3 years . Added a blue throat trigger a month ago then two weeks later added 2 tangs . All fish have been eating and active . A week ago a started loosing fish . Blue throat, yellow eye tang, flame angel, and a saddle back clown . Water quality is good RO unit , reef octopus skimmer ,20 Gallon sump . Running metal halides 2 of them , with 2 sets of T5s . Water parameters are good . Checked twice by me and fish store . Every day now I wake up to another dead fish . Only one at a time . Porcupine puffer, two Huma Huma triggers, and a flame hawk . I do have soft corals. Any ideas? I’m loosing one fish a day now . I lost flame angel he’s been in tank over a year, lost the saddle back clown also been in tank over a year. Blue throat and yellow eye tang latest additions a month and two weeks ago ?
