Could be, most fish do love those pods
. My clowns all seem to pick at their food though, but do yours actually come out at feeding time and look for the food? As long as there is a good feeding response I wouldnt worry too much about it.
Also, all my clowns are pretty anti social, the two b&w's I have in my 60g hardly ever come out from behind a huge rock in the back, usually only when I feed. Not sure what they get up to back there but they love it there. lol My black one in the 90g also stays to the very left top of my tank and hardly ever comes out unless he is looking for food. lol My most social paiar are in my 125g, they tend to stya in the right far hand corner in the back but come out for food and maybe 30% of the rest of the time. They are goofy little critters
