Any advice would be helpful. I have failed at goldfish and after a long break, my daughters and I have started a new tank. I have a 20 gallon and I started off with 3 orange von rio tetras. I had the orange rios for a week and had my water tested and was cleared to add more fish. Today my daughters picked 2 guppies and we were advised the fish should do well together. Unfortunately, my orange rios appear to be attacking the guppies. I checked on the fish after dinner and one of the guppies had a piece of its tail missing. Not sure what I should do. I have no other heated tank to move the fish to.
Thanks
