LOL Catching fish in a heavily palnted tank? I shutter every time I know I'm going to have to. I have nine zebra danios(minnows with superchargers) I am fixing to remove from my tetra tank and give to my daughter. I am going to try something wierd. I have a very clear plastic one liter water bottle I am going to modify into a mini-minnow trap. Cut off the top funnel. Turn it around into the body of the bottle, then bait it with some food. Attach to some monofilament line to raise it up. As nosey as those zebras are about looking for food, it should work. Might take a few days. LOL I'll keep you posted.
Caudially, OS.
