Hello,

Among marine (even fresh water )fishes which one are most sensitive to
low dissolved oxygen?
when oxygen level goes down in tank which species will first show
change in behaviour ( swiming on the surface, etc).
Which other organism ,zooplanktons etc will show response to change in
oxygen level?

ManyThanks,
