The trouble is it gets very little brine as the tank mates are quicker and greedier.
Has anyone used a feed box for the CBB? See my sketch below.

One would place frozen food in the box and only the CBB with its narrow jaws would be able to eat from it.
Would this work?, provided the CBB is not shit scared of it. Would it become dependent on being fed that way?
I suppose the box could have a suction cup mounted on it like the veggie clip fashion.
