Ok my current three California toads are around three months old and about an inch in size at most. My current worry is I rescued a California toad tadpole from the feeder tank at work before he became food and hes tiny just got his legs and exploring out of the water. Its maybe 1/4 inch. Is there a risk he can be eaten by the big guys?? So far hes being iggnored mostly but he just now like a few minutes ago decided to explore the dirt. They will be moved into a 20 long once I get the divider for the tank. But currently reside in a 15 half land half water. Will small fry be safe or should I move it????
