Update~
I put them in with a LSS cull for the end of their QT period. Kind of early, I know... The little cull is about a year old and not much larger than the juvies are but it now thinks it's king of the world! :D
They seem to be growing out just fine, still eating BH and bits. I'd guess the largest one at about 3 1/4" now...
Hungry little buggars :D
