Roman...I use the Omega One flakes everyday...and I have had NO Problems with them or from them whatsoever...my fish eat them with absolutely no hesitation at all..I've checked the contents of them and several other flake foods and truthfully I would say most are pretty much equal in contents...I can't remember all of them obviously...but the content list on them are all listed in a order like human foods unless I'm mistaken...the first ingredient listed is what it contains most of and so on down the list..as for the bloat issue I haven't run into it at all...I'm sure more will come in and help with their experiences and outlooks on it...hth
