LOL! XD That's okay. ::) It means just don't feed him for awhile. :)
IKR! XD Peachy's just a little a pig. ::)
ROFL!!! XD Jackie thinks it's creepy when Peach flares too. XD
Merry Christmas to you too! :)
It's not uncommon for a new betta not to eat for even more than two weeks! But try fasting him for a day or two then try again. :) I'm sure he'll be okay. ^.^ Does he flare at all?
Yeah they should be. But if I were you I think I'd put Sherlock in the small tank and keep him there until he recovers. :) That way in case he has anything you're not aware of the other two won't get it.
