AMAZONAS
Wataikwa, we found a variant of P. ivantsoffi that had a quince-yellow base color.
I was very excited, but my excitement waned when, after some time in my aquari-
um, they adopted the normal gray base color of all other variants of P. ivantsoffi.
In 2015, just before reaching the Sungai Mimika, we followed a new road
through the freshly cleared rainforest. Eko and I pushed further into the jungle
and came upon a small blackwater stream where we found numerous P. ivantsof-
fi, as well as Mogurnda cingulata, Melanotaenia ogilbyi, and Oxyeleotris nullipora.
Later, back at the hotel, I discovered two specimens of a new species among the
blue-eyes; they were similar to P. pellucidus and P. novaeguineae. Along the middleTop: A displaying male Red Neon
Blue-Eye, Pseudomugil luminatus.
