Been trying to make something to target specific fish to get into and eat some food and the others worked out within 10 mins if they sucked on the end off the tube that they could get the food out through a one way valve. http://m.youtube.com/my_videos#/watch?v=btDxPLbHB2A
Incredible, I thought the average fish had an attention span of a few seconds. Although the fish we had in our pond knew when it was feeding time, only blinkin time you ever saw them ^-^ They're all gone now thanks to the Kookaburras & egrets & I've turned it into a frog habitat.
