I'm Stephanie, and I'm all about creating chill, low-maintenance underwater worlds. My aquascaping journey kicked off in college when I realized I could turn my fish tank into a mini slice of nature. I'm a huge fan of the Walstad method and basically anything that lets me be a bit lazy with my tanks while still keeping them looking awesome. Why fight nature when you can let it do its thing? Lately, I've been obsessed with figuring out how to make Caridina shrimp keeping less of a headache. Everyone's always going on about how finicky these little guys are, but I'm determined to prove that you can keep them happy without turning your life into a never-ending water change.
