RE: [GSAS-Member] pH and gender
Hummm. That's interesting. I was getting a lot of females in my African
broods, where I try to keep the pH high. Maybe I need to lower it to get
more males.

So that's my problem -- my tanks are all acidic, and my Endlers are almost
all males. So how do I gently boost the Ph in my EXTREMELY simple Endler's
tank (2 or 3 gallons, water sprite & hornwort, undergravel filter, & clip on
full-spectrum incandescent for both heat & light.) It's been going without
anything but water changes for several months, so it's definitely on the
acidic side. Since it is such a small tank, I want to GENTLY nudge the ph,
rather than make an abrupt change.
I'd be willing to set up a 10 or 20 gallon for them, if that's what
necessary to make them produce more females.

Fran, if you get down to Seattle give me a call (206-938-1583) and we can
arrange for you to pick up some females.
The Endlers I have seem to be tough little buggers. They thrive on
neglect.
I"ve never had any die.Maybe it's the flouride and other additives in
Seattle water!
