From those turtles, I can learn that they have different personalities.
Sam / Samantha: kind, cheerful, friendly, and doesn't like to attack other turtles.
Sol / Solann : likes to attack, has difficulties in making friends, and fierce.
means sunshine but rarely used.
At first I thought that those two turtles are male, so I named both of them male names (except Sol, because she's naughty, and I just gave her a not really good name that popped the first into my mind ).
Rainy: likes to play, and can spot things easily.
She arrived at my house when it was raining. I adopt it from school, because my school only gave her a small aquarium to live in and with a small space like that she cannot grow well.
Novie: always stays cool and calm, and has no difficulties in making friends.
Emma: always feels shy with new turtles. While the other turtles play (of course without Sol ), she'll stay alone in the corner. If she's with Novie,she's fine, but with Sam, Sol, and Rainy, she's still shy, although it's less now.
Even if they're the same species, my mom and I noticed that Sam, Emma, and Rainy have slanted eyes, while Novie and Sol have round eyes.
