Arkie,
I'll +1 Bill's advice not to spend more on FHM. We might be able to ID the catfish fry if you can net some. Walmart has a bait bucket net that would work for that (has a 1.5 ft or so wooden handle a fair sized net. I have collected BH for the aquarium with it and lots of GAM. I wrapped a broom handle to extend the reach.
Its cool that you were able to buy GAM by the pound. Can you say where they were purchased? or point me to its website?
I am hoping you are not dealing with FH or BH for the catfish. I will say I was just looking for BH spawn just yesterday and I have yet to find any in the DFW area. Not sure how your location in AR compares (earlier or later than here) but I usually do not see BH fry until late June or early July here. That there were two fish were caring for the young sounds like BH though.
FHM are very vulnerable to small LMB. But everything eats FHM including CNBG. FHM males are VERY VERY vulnerable due to their nest tending and guarding. Without successful reproduction, FHM soon are gone. The GAM, even though you stocked only 1 lb could replace the 40 lbs FHM.
