Thanks! I know it....no I am not a 100% sure, but I think a possible bacterial infection. The fins on both were torn. No aggression in my tank, but they would dart around a lot, wondering if they had gotten injured and developed a bacterial infection from that? Only thing I can think of. That's the frustrating part besides loosing them.Ouch. Did you find the cause of his death? Sorry for your loss!
Im so sorry for your loss @Qasimja .Well its been 2 days since the yellow tang died no other fish has any problems they are all still eating and acting normally no visible signs of disease no hiding from the lights or swimming into powerheads
