I must agree with this--I've really noticed how amazing the change is:
the fish really perk up in a tank with live plants (even beyond that which
O2 would explain: I have very light bio-loads). Even in a tetra-only tank,
many of my tetras are constantly "hanging around" the live plants, at
the discrimination of the plastic plants. After introducing live floating
plants, many of my fish that had spent ALL their time in the bottom 1/3
of the tank now spend ALL their time at the water surface, just under a
leaf or clump of vegetation. I was shocked! (A really good example is
my emperor tetras [Nematobrycon palmeri] or my female Betta splendens at
work.) They really seem to desire exploration through a jungle of
vegetation ...even when it appears they are not foraging.
I didn't realize plants encourage slime coat production or protect against
diseases, though. I wonder if that is merely a result of lower environmental
stress? I'm trying to figure out the biological component...
Some of my fish seem to really enjoy "rubbing" through live plants, though.
(No, we don't have ick! :-) Do you think this may have something to do
with slime coat production? It seems to almost be a method of grooming
or self-cleaning, like many mammals exhibit. I don't see this behavior
with the plastic plants in the same or different tanks.
Any additional notes on unique fauna behavior in planted aquaria?
