tetra prima is good for all fish because it contains enough protein for most fish and has natural enhancers n it to promote colour and growth you can get it in a fine granule or a larger one for bigger fish so i would reccomend for all AMERICAN cichlids then you could use cichlid gold for the larger types of cichlid but prima will be more than good enough for your angels... and neons would be an expensive meal and not really a good thing to do unless you are rich and sadistic
