Hi, I have a 1/2 gallon for my betta and I tried putting in some ghost shrimp with him. As soon as he saw them he would chase them around the tank. The shrimp were insanely fast, but eventually he killed both after two days. Is this a sign that he won't do well in a community tank? I was planning on moving him to one after I got a 5.5g or 10g tank.
