I have one of each known dat except for the ST,two indos actually and they all have taken to eating the freeze dried krill except my NGT and AT and they are the smallest and probablyyoungest of the group.The AT sometimes will take a small peice of krill that has been blown around in the filter current but that will be as far as it goes.I tried starving but I think that is what took out the other NGT that I had.If I can convert these two thats one less tank to dump feeders into.HELP.
