they were caught in my yard after some rain where the puddle was drying up, All were the same size and looked the same but 3 grew really fast and 3 weeks or so and they were little morphs, now they are grown alot more like almost growing to adult size, and very healthy frogs eating well. The others did not grow but stayed small and have been since. im not sure why they they look the same as the other ones did the only thing thats changed is it has got colder in weather.
