This is upsetting!!! GRRRR. WHere did you purchase the frog from? Please make testimonial in the testimonial section on this website. Thats 2 unsuccessfull RETF stories this week. Im not happy. Jeppie I am a RETF breeder and i would like to offer you one of mine come JUNE if you are on the WEST COAST. Im very sorry it did not work out. I still stand by my statement of a cut / amputated toe. However it did look treatable... One thing to keep in mind when you have a sick or injured frog is not to handle them much. I see you did what you had to do to show us pictures so we can see what the problem is. =/ I agree with heather and that you had a nice setup...I would invest in a TALLER tank though for Tree frogs with Larger leaf plants. They love to climb and its just not the proper tank for that type of frog. I wish you the best of luck and keep in touch with us so we can continue to help you on your journey of living with RETF's.
