Two fish out of the ten I bought died. They looked sickly when I bought them. They had kind of a hunch back and a sunken stomach, probably were never going to live much longer under any circumstances. On the other hand four of my lettuces are growing quite well. One started to grow and then petered out, not too sure what happened to that little guy. The last set of seeds never sprouted at all. I put two new seeds in that spot and we will see what happens!
