Hi! My name is Tommy Kronkvist. I'm a Swedish amateur ichthyologist born in Finland, with a special interest in Nothobranchiinae from Western and Eastern Africa. I used to be the editor-in-chief of Aqua Upsaliensis, a monthly magazine focusing on marine life and fish farming active between 1965 and the late 1990s.
My first edit to Wikispecies was made back in May 29, 2005 when I created the user page you're reading right now. That was exactly two months after my very first Wikimedia edit in March 29 the same year, when I created the page Nothobranchius at the Swedish Wikipedia. Thirteen years later (August 30, 2018) I created the Wikispecies page Danio tinwini which also constitutes as my 100,000th contribution to the community. In May 30, 2021 I made my 100,000th edit to Wikidata, about the German magazine Tropical Fish Hobbyist. In May 2, 2023 I made my 300,000th edit to Wikimedia, when I created the article Siri (programvara) – about Apple's Siri virtual assistant – at the Swedish Wikipedia.
My global account information for all of Wikimedia can be found here.
Last but not least I'm 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.)
A few of my Wikimedia Commons images:
Nothobranchius rachovii is an East African freshwater species of killifish in the order Cyprinodontiformes I used to breed. The picture shows an adult, male specimen hatched, brought up, and photographed in one of my aquaria.
Snake Plant, also known as Mother-in-law's Tongue (Sansevieria trifasciata), here with flower buds on my window sill.
Adult male of Mexican Dwarf Crayfish (Cambarellus patzcuarensis), 4th generation bred in my aquaria. The body is about 3.5 centimetres long (approximately 1.38 inches) excluding the claws.
