The slowest :P of the fishsupply siblings is finally making some progress. he is now hunting frozen shrimp on a feeding stick. If I move it around he will come out and stalk it. Eventually, I let him catch it. It is interesting that he does not like to let go of the acrylic feeding stick. If I keep wiggling it he will try his hardest to pull it out of my hands even after he has the shrimp. (maybe he thinks that it is the shrimp struggling.
Anyway, I got some good pics of this psuedo-hunt. In the one you can see him grabbing the shrimp. Hopefully, he will "graduate" to catching live shrimp in the near future.
