Thanks ewest. Yes, those are they.

The stockers I bought are between 3 and 4 inches now. The adults we moved have been spawning for weeks and look very healthy. The adults ranged between 5 - 7 inches when I transferred them, and it looks like I've got some 8 - 9 inchers now. They've had access to large numbers of FH in all sizes since they were stocked in late April.

Some of the larger RES have been eating a few dozen maggots every day for a while too. \:\)
