The best thing about the new content added to Genshin Impact is exploring all the smaller features that come with it. Thanks to the Omni-Ubiquity Net, you can now capture several different types of creatures for your Serenitea Pot. Enkanomiya introduces a world of strange new creatures, so it's no surprise that players try to capture them.
There's a bit of bad news when it comes to Enkanomiya creatures you can bring home. There aren't many animals that you can currently bring with you in your Serenitea jar. For starters, you can't catch the floating manta rays that glide around the islands, nor can you catch the schools of ghost fish.

In fact, the only new creature you'll really be bringing home is the Deep Sea Unagi. This is likely due to the ghost fish acting more like a puzzle solving mechanism to get you to the portals. Floating rays would be a bit difficult to control or navigate through your Serenitea Pot.
