There are many people in the world who have pets, but not many have pet frogs. One of the easiest frogs to take care of are Amazon Milk frogs. 

Amazon Milk frogs have blue blood and that is why they have a blue tint to them. The females are louder than the males and since they are more active at night, the females can be difficult to have in the same room with you as you sleep. 

The reasons that they are such good pets for beginners is because they require little maintenance. Amazon Milk frogs require a tank, a substrate, plants, water, and food. A substrate is something that absorbs the moisture from the tank and can keep the humidity levels right. The tank should be 18 by 18 by 24. The substrate can be as simple as a paper towel as well. The substrate goes on the bottom of the tank and can provide a layer of cushion for them as well as soak up moisture. They need plants so they can climb on and water so that they can keep damp and drink. 

One very important thing to keep in mind is handling the frog. Human hands have chemicals that can be harmful to the Amazon Milk Frogs, so it is important to wear gloves when touching or handling them. They also do not like to be held for a long period of time. 

Amazon Milk frogs are also able to live in packs. They are friendly to other frogs and do not create problems. Male frogs and female frogs however, can cause problems. The males can become violent to the other males when a female is present. So I would recommend just getting all males since they make less noise. 

Overall, Amazon Milk Frogs are good pets and are easy to take care of for a first time frog owner.
