Sudden death of 3 fish - please help!
I have a 240 litre jewel aquarium with 2 external filters, 2 powerheads, skimmer, live rock & live sand was inhabited by
Pair of maroon clownfish
All living happily together no signs of disease and feeding well.
Suddenly today the rabbitfish, yellow tang & fairy wrasse were all foun d dead at the bottom of the tank all very close to each other. PH, Nitrates, Temp & salinity are all ok. The Carke's was looking unweel but now seems to have recovered.
I know its a long shot, but any ideas? Could the rabbitfish have posioned the other 2 and itself?
