Giving Back
Over 28 species of wild Betta have been assessed by the IUCN as endangered or critically endangered as of 2019. In 2015 we established the Castle Dawn Aquatics Betta Rescue program, where 20% of the profit from any Betta-related product went back into wild Betta conservation. We are thrilled to be extending this program to our online sales with the relaunch of our new website.
