One of my favourite aquarium books is William T. Innes “Aquarium Highlights” from 1951. I bought it second hand at a dealer of antiquarian books in Oxford when I studied there in 1968. In it, there is a small chapter by Michael Tweedie, the former curator of the Raffles Museum in Singapore, writing on a small fish called P. deissneri (but it was not deissneri, as we know now). This was my first encounter with that fish.
I wonder: Nowadays, a long time since Innes and Tweedie have passed away, does Parosphromenusoccur in American aquarium literature, especially the magazines? They rarely do in European journals, too, but one and then one can read about them. And afterwards there are always people who are interested and ask where to get that fish.
