I must say, though, that it's refreshing to see that you don't
correspond to the "You can't tell the sex of an Oscar" internet
newsgroup bandwagon! This is the second most believed and propogated
Newsgroup fib -- the number one myth, is, of course, the newsgroup
weekly water change myth. (You've heard it, I'm sure -- "If you don't
do a partial water change weekly, all your fish will die"--)

You can't be CERTAIN of an Oscar's sex without a blood test or
witnessing spawning, but experienced keepers notice characteristics
that are more typical of one sex vs. the other. Not a certainty, but
experts can look and be fairly sure.

It's similar to the water change myth. Weekly water changes are not
usually required, but they do improve the chances of fish staying
healthy. A weekly water change isn't really necessary for a
reasonably stocked tank, but it can help.

A third major aquarium myth is " you have to use CO2 injection to have
healthy plants." I've never used CO2 in my current tanks. My largest
sword plant is a little over 3 feet across and 2 feet tall, with
about 10 baby plants growing on it. I grew a 40 gallon hair grass
"forest" from 3 small rhizomes, and I have Java Ferns nearly the size
of a basketball.

Keith,
Would you care to elaborate on your setup?
Lighting, substrate, bio-load, etc...

I want to plant some tanks (55g-75g,) and will not be using Co2.

thanks
