Thanks for the replies about feeding, guys.
Yea, I intend to get some small plastic tanks for feeding them separately in, as I'd read ages ago about accidental injuries from feeding together, and that doing feedings in smaller separate tanks is recommended to prevent this, and to prevent any dirt/shavings from getting into their digestion accidentally, since the tanks can be empty.
I'll be teaching my brother to do the same when he gets his little guys, too.

I know Reggie can be such a ditz when it comes to feeding that he'll bite my hand, or the tongs if I'm using those, instead of the food, so I wouldn't trust him not to be a dummy about his new friends' food either.
