Fish are kept in refug for 2 weeks . Added several fish at once to avoid any selectivity form aggressive species.
Lost 3 clowns on 2 separate occasions over 3 week period . Added 3 cardinals and a yellow wrasse at one time .They seemed compatible in the sump and did well for 3 weeks then slowly the cardinals would go missing one at a time over a period of 2 weeks . The wrasse I did not see after the 2nd day.
I would doubt it was water quality as all of sps etc are very healthy and growing.
