What sort of clown is this?

[SmallFry]

Ok, so I'm hoping to tap into some fishy expertise out there.. I bought my clownfish a bit over a year ago, I reckon he's now about 2" long. I bought him as a tomato clown, but as time has gone by he doesn't seem to have darkened any. All the pictures I have seen of tomato clowns are very dark, so I'm beginning to wonder if he really is a tomato clown or perhaps something similar.. This is what he looks like now:



I was wondering whether he may be a Fiji Barberi clownfish like this:

The only difference I can see is that mine has a black line on the leading edge of the pectoral fins which the Barberi in the picture doesn't.

I'd really like to know what he is, because I was thinking of trying to pair him when I upgrade my tank to a 75 gallon, but I've no idea what'll happen if I try to pair him with something he isn't..

If anyone can shed some light on what he is or what the implications would be if I paired him with another clownfish of a slightly different species I'd be really grateful.

Thanks,
Rob.
