No his fins never seem to flare, none of them do. He does move around a lot faster when they're fed, I just put that down to food being put in there. The fins were together like that when I got him, it's not his anal or dorsal fins...it's the ventral fins that go down under the pectoral fins. He stays quite close to the other 2 at all times, and has never isolated himself (which the platinum did when it was added). Length his body his 1.5 inches add the caudal fin and it's about 3.5 - 4 inches long (his tail - as my son calls it - is soooo much longer than him) and from top of dorsal to bottom anal fin he's about 4 inches.
