Hello I have a fairly new tank, 3 to 4 weeks old, i upsized from a smaller tank and used some rock from that tank and put it in the sump to add bacteria for the new tank. The problem is I've had two fish die (Cori's wrasse, blue Tang)recently with no signs of ick or parasites. The other fish (clown, yellow Tang and goby are fine and healthy). I'm wondering if this is due to the new tank or something I'm missing. 65 gal with 20 gal sump. Parameters are near perfect, temp 78.5, salinity 1.025.
