Petey's head seems large for his tail size but that may a camera perspective. When I first saw the yoyo, I thought he may be a king leopard or queen arabesque? I've had scribble plecs that had similar coloring to your loach. Sorry, again, to be so lame.
How big is Petey? I've had clown plecs several times & they maxed out at maybe 3 inches or so at most. Mine were quite long lived, ~8-11 years.
