Most of my wiki-work contributes to Wikispecies, where I'm an administrator, bureaucrat and interface administrator,(verify) the Swedish language version of Wikivoyage where I'm an admin and interface administrator,(verify) and to the Swedish(user page) and English(user page) language versions of Wikipedia. Since 2021 I'm also one of the administrators at Wikimedia Sverige,(verify) i.e. the national Wikimedia chapter of Sweden that hosted Wikimania 2019 in Stockholm. Last but not least I am registered at Phabricator, a development collaboration tool used for Wiki software development, and administer the official Wikispecies Twitter account. (My personal Twitter account can be found here: PixelHermit.)
I employ the same username throughout all of the Wikimedia community, and my global account information for all of Wikimedia can be found here.
A few of my Wikimedia Commons images (click for larger versions):

Bluefin Notho, another African killifish I used to breed, here photographed in one of my aquaria.
Two male Blue Gularis, a semi-annual killifish in the order Cyprinodontiformes. Here shown during an exhibition in Stockholm.
My Persian cat Chapman af Leufsta, or more casually "Chappe". He passed away in his home in December 2006, six weeks after his fifteenth birthday.
Adult male of Mexican dwarf crayfish, Cambarellus patzcuarensis. The body is only about 3.5 centimetres long (approximately 1.38 inches). This one seems to be chatting with one of my Great ramshorn snails.
