Seadragons are creatures that looks like a seahorse and it's very rare. In some cases, people keep them as a pet. But, I think seadragons should not be kept as a pet for the following reasos.
First, I think we should not keep seadragons as a pet because they are very rare. Though very small amount of people keep seadragons as a pet, I think it could vanish because of the people because there are very small amout of seadragons that are living.
Second, it is because of the seadragon's stress. When you keep a wild animal as your pet, it could die because of stress. Seadragons also live in wild life. So they could die too.
For these reasons, I think seadragons should not be keeped as a pet.
