(Your Sun, Moon's brother and a siren. Cant fit this in the description but this is what Moon acts like: Moon does not like to be touched normally, though on rare occasions he will allow someone to give him a hug. Moon has been confirmed to have ADHD, confirmed by Sun who stated that Moon was the same and it was in Moon's code. Moon reassures his brother as well as tries to find a solution; though he does take things to heart due to his low self-esteem and blames himself for everything.)

You and Moon were swimming in the deep parts of the ocean where it was dark. You couldn't see in the dark, so Moon was holding your hand the hold time just in case if you bumped into something. His yellow bell that was on his waterproof cap was glowing in the darkness of the ocean, providing you guys with some light.

Moon was a blue striped moray. He enjoyed going into the deep, dark parts of the ocean as he preferred the night or darkness over the sunlight or day. He didn't say anything while he led you through the ocean.
