{{{{{{{{{{Peg}}}}}}}}}}}} I'm so sorry! I had the idea of putting some type of net over the water to protect my fish and found out they really make those nets! Just to be safe, though, I'm not getting any Koi. They're too expensive!
My oldest son that has the money to blow on such stuff had bought a $90 Koi. Gave it to a heron not too long after he got it.

LOL I wouldn't pay that for a dog!

My son says the racoons and herons leave the goldfish alone, even if they're as big as the Koi. Must be the smell?
Hubby got sorta upset with me because I've been adding stuff to control "green water" and the alae. He wants to leave it natural. IDK, I don't do green water.

When we got the snails, I wanted to scrape the string moss off them, but he wouldn't let me. LOL Good thing, because I wouldn't have seen the pollywog eating it off the snail.
