purple tinted yellow pseudochromis

[Midwest Express]

Hey Everyone,

Just a quick question on a fish I have.  I have had this fish for a long time.  I can't what I was told it is.  To me he looks like a normal yellow pseudochromis but when I look for pics that match him they do in body shape but not color.  He looks like a normal yellow pseudo but dorsal fin down to mid side and the length of his body has a purple tint to it.  I can't find a pick of him online anywhere.  He is about 4-5" long right now.  I will take a pic of him when I get home and post it on here tonight.

Any thoughts as to if he is different than a normal yellow pseudochromis of just a color variation on one or a different fish all together.
