PBBs are at 14-16 inches long and still very skinny. They just got dewormed. As on how to tell the difference well, fin count don't usually apply as some PBB have only have 14 finlets some have 18. Same goes with lap at 13 but max at 15 finlets. When the finlets pass 15 then it's a 100% PBB. Also the distance of the eyes between each other of a pbb is a bit farther away from each other. While laps eyes are set almost on top and are closer compare to PBB. The lower lips of PBB are also thicker and more protruding than laps. Once I get my PBB to fatten up I will post a tread on comparison with different lap variants as some laps such as bullets head have similar looks to PBB.
