that tail/ tail color is a good indicator... its lacking the typical jurnese type pattern but judging by the size of the pump pictured behind it just seems like its a small specimen whose pattern didnt come in yet. B. rousseauxxii would b a stark silver/chrome colored. every jur ive seen/owned has that purple/blue/black base like the one uve pictured. finnage/head/body shape is all correct for jurnese also.
