They were only in water. No soil. And I did not feed them. But I did put them in a branch of the same river from which they were harvested, on private property. I also gave about 50 away. There were more than I thought--about 140-150 total. I'm sorry I didn't post sooner. I really wanted to get rid of them quickly. There was really no way to take care of them. I kept 3.
I have never in my life seen such a thing. It has been exceptionally rainy here. I am sure the people are still selling them as bait but I won't look again. I can't handle it. They are asking 50 cents each. If anyone is interested I can give you their contact info.
