Re: Sexing regani

["Susanne and Cory Williamson" <webwill@infinet.net>]

Mike,

I agree- I have often found even biologists get lost in the color of fishes-
mostly the problem is ignoring the whole picture and not using all of the
features in combination with color to make an ID. Ever try differentiating
young salmonids?  Right now my limited knowlege of Apistos and lack of
literature is confusing the matter for me. The books Apisto books I have
paroused (at the LFS- since I can't afford the outrageous prices they are
charging- min $50) have shown various Apistos without showing any decent
comparartive anatomy.  What I need is a good well designed dichotomous key
for the Apistogramma. Does such a thing exist (at least for the described
species (or even the common ones)? I don't recall that Linke & Staeck
describe the differences between the regani sexes (am I wrong). I have a
keen eye for this sort of biological minutia- but I am lacking the necessary
information to make the call.  Is there a biological paper ( or somthing
like this) that describes regani in detail. I am basically fairly certain
that the three reganis that are similar are males- but I have a pair of A.
borelli in the same tank and the three regani have behaviours that are more
like the female borelli (in terms of activity as well as color markings) I
assumed that Apistos would maintain behaviours peculiar to each sex across
species (Bad assumption?).

The one thing that is still clear is that I have no idea- but thanks just
the same, I appreciate the help-
I think these Apistos are very cool!
