I did something strange! I live in Ohio and I put out a saltwater pond. It is small about 100 gal. I did water changes on my main tanks and redid my one cuttlefish tank so I dumped all the water into an outdoor pond in my front yard. I wanted to find a place to keep all my feeder fish anyway. Sheep head minnows, mollies and cleaner shrimp. Plan to add mysid shrimp and amphapods, copods. Should be interesting. Running out of room in my house!
