This is may be true in my humble beginner experience. I have terminal high pH that I am unable to change (yet I get free swimming rams in it). According to the data, I should have more females with my high pH. I worried because, how am I gonna sell a bunch of little brown fish to the LFS. I got a good ratio of more males to females by raising the temps. I may have totally balled this up so have mercy and do not flame me. Thanks Teresa. ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@listbox.com.
