Since starting my aquaponics system, it has been visited and in some cases occupied by all kinds of creatures. I was especially happy to see 4 tree frogs spying me from my raft beds, but I am a little ambivalent about the aquatic snails that have set up shop. They seem to be munching the algae mostly, but now I have them hanging out on my plant roots... not sure if I should take some action, or wait to see how this plays out. Any advice other than sterilizing my entire system.
I have chickens, but they have no interest in slugs, which I hear is often the case. My duck plans didn't work out this year. I'd love to have guinea hens to help deal with the tick/Lyme disease issue. Of course, all backyard poultry are illegal in my rural town. Go figure.
