I'm lucky to have never had to give anyone a time out, although when Lotus got some buoyancy issues from over-eating I believe, I did bag her just for a few seconds so I could feed the others.
They're so weird. All of them but Lotus crowd into the corner when I feed them, so when I spread out the food, 5 of the girls only get the food in that ONE CORNER and Lotus goes around and gets the rest of the food that's NOT in that corner. So that's why she had SBD issues -_- She's also the only one who will eat the pellets as they're sinking.
She's always been my "loner" girl. When I first introduced them, she found a little corner for herself and swam around there. The other girls couldn't see her so she didn't get disturbed.
I guess I got lucky. Lotus and Stella are my two EE siblings, Daihatsu, Ascari, and Kuraokami are my dragon siblings, and Mercy, my purple girl with no siblings, is my "peacemaker". She's the only one the aggressor won't chase. She'll break up fights but she won't chase/nip others unless they're aggressive first.
