I picked up 4 young Laetacara araguaiae - should probably take a few pictures once they are adjusted. Basically what I think will be two pairs (but they are not mature yet) for my 40B. They seem to have a bit of subtle colouring even though they are not full grown but i'm not sure they are as docile as the lit suggest as the two males were chasing each other a bit. Seems the smaller male is a bit more aggressive than the larger one. I couldn't find one of the females at feeding time but she might still be settling in. Hopefully she will turn up for breakfast....
