Not a diamond tetra?
 
I recently bought 3 more diamond tetras as i had a school of 4 (originally 6 but 2 were killed by a firemouth) to increase the number to 7. Well i just noticed this but it looks like the guy at the lfs scooped the wrong fish by mistake (was supposed to only be diamond tetras in the tank). Maybe the little guy jumped from his original tank? He looks tattooed and very similar to a diamond but there are some distinctions that make me question whether he is or not. He is happily schooling with the diamonds and what not so it doesn't appear to be a big deal. I just would like to find out the type of tetra he is or if he really is a diamond tetra.

I agree with Quantum. Phil, click the shaded name to see the profile, the photos have the answer to your last question.

If it were me, I would return this fish and get a true diamond. Singly fish of a species often get very stressed and this can cause poor health, disease or aggression beyond normal--in time. I know, I've experienced it and had to destroy fish.

The problem with this is the lfs I got him from is more then an hour away. I think we are planning another trip down there to eventually switch out our small gibbicep pleco for a smaller species and get more panda garra to get a larger school but that could be a few weeks down the road. If he starts to look bad ill donate him to a local pet suppermarket who takes in fish and just keep to 6 diamond tetras.

Keep a close eye, as it says in the profile this species is reported to nip fins, and this sort of aggression is what can be elevated under stress. The diamonds are a sitting target.
