I keep a heavy fish load. Typically, my tanks carry just about an inch per
gallon, and often more than that (depending on how you count the bottom
feeders and smaller fish).
As for the 'other problems' each of you refer to -- I'm sure they come into
play, but I haven't seen disaster strike my tanks as a result. We tend to
overfeed; my husband and I both feed the tanks, so sometimes they get an
extra meal, as a result. Not to mention, I've got a lot of bottom feeders,
and I tend to give a little extra pinch, to make sure it reaches down to
them. My fish seem to achieve full growth, or at least as much growth as
less-stocked tanks I've known. I don't often get disease outbreaks, and
when I do, I blame my lack of a quarantine tank, not my fish load. I don't
have serious algae problems; again, I've discovered other reasons for the
outbreaks I've had.
Perhaps it's not such a problem because I plant heavily with fast-growing
bunch plants? Perhaps it's the weekly water changes?
