I appreciate your response. It didn't occur to me that a paralyzed frog might be at risk with a companion frog, so it makes me feel better about my frog being alone. I did think I had a bullfrog, but I read they get to 8 inches long. My frog is no more than 3 inches and I just can't match the coloring and markings to anything. I'll keep doing what I can to keep it safe and comfortable, for as long as it lives. Thanks for your help.
