Seeking rain barrel goldfish advice
Three recycled plastic rain barrels just arrived, & I’m about to connect them to my gutter downspouts. I’ve heard that some people keep goldfish in their rain barrels to eat mosquitoes. First, how do I keep them from getting too hot? Secondly, do I need to feed them otherwise? And, lastly, is this a real thing? I want to be able to water my veggies and perennials more sustainably, especially since we’re in a drought where I live.
