I thought the word skimmer came about from the fact that you could skim them over the surface whilst landing them? Therefore, most silver bream are skimmers because silvers tend to be smaller, but common or bronze bream can also be skimmers when they are little uns?
Ive always classed a bronzy brown common bream as a bream. A small silver common bream a skimmer.
Isnt it that the common bream goes through changes as it reaches adult maturity and changes into a darker colour???
