Sorry no I did not know what species of frog u had thats why I asked
Yes they will eat eachother if they are hungry and can fit them in thier mouths. Its always best to house same species of around same size. Im sorry for you loss!
Could the anoles have eaten it I've heard of salamanders and frogs eating eachother?
What size terrarium? make sure you dont cram them I've been told 10gallons per frog and since you have mixed species the might need more to avoid stress and aggression.
Hope this helped =)
