Went to bed Tuesday night Reef was ok. Woke up Wed. morning to a "Fish Kill". 13 Fish had Died. All Coral and tank pumps were all O.K. I lost 2 Scotts 1 Rosey Scale Fairy,1 Copperband, 2 Filaments wrasse, Large Cardinal Bangiee 3 years old,2 blue sided wrasse,1 double spoted blennie, 3 Veiltail Anthais. All else is fine in the tank. Bubble tips are all open. One pearl wrasse, one bi-colore blennie and a pair of clown are the only fish to make it. After I did a water change today the Clowns laid more eggs. Maybe they will grow, since there are no other fish in the tank. I check the tank perimeter and all is well.the mysterie still continues. The tank has been running for 3 years with no proplems ??? what a way to end 2008..I so happy 2008 is finaly over. :-\
