We have had a mysterious fish die off. One week it was a diamond goby. The next thing on Monday I found a dead anthias. All seemed well for the next four days when after the usual water change of 20% the next day we lost a yellow and hippo tang along with another chromis. The clownfish seem OK. The tank parameters are fine along with all the coral. I did notice that the DT'S kept in the refridgerator was a bit smelly. The tank and the fish had all been doing fine for a year. Thanks in advance. Any help would be great.
