My kids adopted two FBT and we have been taking care of them for about 6 months now. They are fun to watch...I have to admit!! Ever since we got them the smaller brown one mounts the larger green one all the time and they chirp constantly. I can't tell if they are both chirping or just the brown one. A couple weeks ago we saw the smaller brown one on top of the green one for HOURS. He would not let go and the green one just carried on with this frog on her back all day long. He just wouldn't let go. So now she's VERY fat (I'm saying he/she just because I don't know any different)...practically buldging and I wonder if she could have eggs? I really am not interested in breeding them, but I'm a mother and if this girl has gotten herself "into trouble" then I want to help her and do what is best to carry this through. Plus the kids will learn a lot!!! How long are they "pregnant?" Or maybe she's just going through a fat stage? The information out there is not real helpful. Thanks a lot!!
Mating behavior doesn't necessarily mean you'll get eggs. FBTs will do that constantly with no results. It is entirely possible that you have two males. They don't really care who they're on top of. However, it is possible that you have a male and a female, and that she will lay eggs. Frogs and toads don't 'get pregnant' in the usual sense of the words. They become gravid, meaning they are full eggs, and the eggs are fertilized by the male as they are laid. A single female can lay over 200 eggs. If you find yourself overwhelmed with eggs, there is nothing wrong with disposing of some (or all) of them. It can be hard to feed, house, and find new homes for all the offspring. If you decide to keep the eggs, they should be removed from the tank and kept in a separate tank at about 77ยบ F. They will hatch in 3 days. For the next few days, the tadpoles won't be very active while they use up the last of their yolk. After that, they can be fed fish food- flakes, frozen or freeze dried. They will start getting legs in week 3, front legs in week 4, and be ready to leave the water in week 5. The young frogs will need small insects to eat, such as very small crickets and fruit flies. The small toads should be kept separate from the adults until they are too big to fit into the parents' mouths. Hopefully that helps.
