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,

homework question. Are you a student? Do we do homework assistance

Hmmm, good question, student or not? If student, I'd go google, as we don't
get that detailed here. Bascially what we can tell you, is with low O2 the
bigger fish, of the carp variety, die first. ~ jan
