pbass, That why i said i was " introducing " . Obviously they are always down to eat, so i gave em a few of the "plankton" and when they came up for more i tossed in a diced cube of the tilapia, he ate it, took it down and seemed cool with it, but apon the next grab he spit it out and was all set with it. I like to dump a few feeders in there just to let em have some fun, and admire their quickness and insatiable appetite. Just figured if I could expose em to it now, that way they will be more receptive to it when they gotta start eating it primarily, i only mentioned it as either a reason for disliking me now, or maybe the tilapia wasnt sitting well with him. I am not too concerned about their diet as apposed to the drastic change in personality and color.
