OK, "fishing" by simply attaching a piecwe of shrimp to a lenght of a line does not work. Since there is no weight, bait simply floats, and each time you jerk the line shimp hardly moves. My fish did not react in any way other than giving me a look of digust, as if they were saying "hey man, WTF is wrong with you?!"
I could ofcourse put together a real "aquarium fishing rig" with a weight and all. I'm just afraid that fish with end up swallowing that little weight or something. I will try to go with the Plan B now: will get a feeding stick from Pet Solutions and hopefully it will work
