Mine are quite boring meanings compared to all yours but i'll add them anyway :)
Aden - Little Fire/ Handsome - He was my first betta but sadly he died :(
Clark Gable - First he was called Sorbet because he looked like raspberry ripple ice cream at the time but as the months went on he marbled and a pencil line moustache became more prominent so I re-named him Clark Gable as he had one of the most famous pencil line moustaches in hollywood :)
India - I could't think of a name for her so my sister called her indigo because of her colouring, Indigo didn't feel right so I named her India :)
Angel - She was the only female in the tank at the time that didn't fight with the others so I called her my little angel because she was so well behaved but that has now changed lol
Molly - I just liked the name, she is my suicidal fish that always jumps out of the tank when I lift the lid
Missy - She was clearly the "top dog" in the tank so I thought the name fit perfectly as she was a proper little madame :)
Tinie - Tinie was my last addition to the tank and also the smallest, when i got her she was only four months old and compared to the others in the tank she was.... well tiny, so I changed the spelling a bit and kept the name :)
Sam: I don't know, I was really young
Napoleon: a warrior? I'm not really sure why I named him this
Apollo: god of prophecy, medicine, music, art, law, beauty, wisdom, the sun and light
Comet: eh just came to me to name her
Kronos: Titan lord. Honestly I named him that because I have a Greek theme and he made my bettas spell "SNACK" (lol). I needed a "K" name and there it was
Irene: peace. She was really peaceful and even though I only called her "Girlie" anyway she needed a real name
Titan: ehh...it was Greek, the titans are fierce so Titan came to be
Kreios: lord, master. He was Deimos, but it didn't really fit him after a while
Deimos: terror. I didn't get the name from CR, actually
Phobos: fear, panic. My dad was looking on the BBC news and there was something about Mars' moon Phobos. I asked what the other moon was and he said Deimos! So I thought it would be kind of funny to have both of Mars' moons.
Gooberfish - fish native to the planet of Naboo He's a blue VT.
Helios - personification of the sun in Greek mythology, sometimes another name for Apollo. He's a yellow crowntail. I let my husband name him, and thankfully I managed to convince him to go with the second choice. His first choice was Bill. Not that there's anything wrong with Bill, I just didn't think he looked like a Bill.
