Thank you both very much, it means so much to me to have such a knowledgeable community to turn to for help.

I have plans to buy a 10 gallon tank with a nice filter system soon this week for him since after reading the information Mattsmommy2 provided I have realized I need better equipment. I was curious though Dr.Barb if my other frog could get this red leg infection also. He shows no redness at all right now, is swimming very strongly and eating well but the infection came on so suddenly with my last sweetheart that I fear he might also get it. If this is possible what should I do to prevent it?

Once again thank you so much.
