They seem fine with my cherries, propinquas and malawas.They right about the same size (length, smaller in profile) as the adults. And their mouth is so small can't imagine anything more then a couple week old could possibly be eaten. Mine seem to be all over the tank spending lots of time playing in the filter outflow. Definitely a fun little fish in a low light heavy planted tank. Oddly they seem to shoal with the habrosus a bit. cool indeed.
