So if I set up the rain barrels under a gutter spout on the chicken coop, I can collect roof rain water. I was wondering, as a kid we all used actual wood coated with thick wax barrels, but nowadays they've got the plastic. One thing I noticed, when water is in plastic, it slimes up faster.
Would you add fish to a particular type of barrel? Also, what do you feed the fish? I mentioned this to DH & he shook his head...said I'm not a good candidate for that, he says I start out all logical & talking about efficiency & function, but in time my attachment grows, so all I'm doing is adding another "pet" to my menagerie to care for & worry about.

He may have a point, there, I used to have tropical fish tanks growing up, also turtles, newts, frogs...Do I get a bit carried away? Maybe.
