I have been wondering about this for some time..I have always heard and read the zoa's and paly's feed off the water column..for the past month i have been target feeding mine and have noticed a uptake in growth in all my zoa's and paly's..different varations take the food different than the next one. for example..my captian america and purple death palyscomplete engulf mysis shrimp.where as my green bay packers like it diced up more finer..feel free to chime in on this subject if you have experienced this or just have a comment in general
