New animals in the mangrove swamp

I think there are new animals in the newly added mangrove swamp.
The first is Pygmy hippopotamus, which is designated as an endangered species.
Most of the day, they live underwater and are friendly mobs that spend time in groups.
And the large fish "catfish" is also good.
This mob has a strong appetite and eats tadpoles, frogs, and even axolotl.
However, catfish can be eaten as food like other fish.
If you have any other good ideas, please let us know in the comments.
Thank you for taking a look at my idea.
