perhaps a brandtii? Some one mentioned spilo cf? I hope it ain't something cheap cause it cost an arm and a leg!

Nope not a brantii IMO. I want frank to give his opinion first. Again, like I said before, I may have a new ID for you. I am not pro at ID'ing fish, but this one looks very similar to a fish I see quite often. I think perhaps frank might have some good news for you. What size is this fish?

It has the appearance of S. altuvei, but the spotting is a bit off for the size of the fish. A better flank photo would be best for another look before making the determination of species.

Exactyl what I was thinking also. Just needed Frank to give his opinion. If it does turn out to be an altuevei, it will be much better then a rhom. I have one. Mine is 7 inches. Thats what I was refering to as me seeing a similar fish often. We will see though, please post more pics. Flank is the back half of the fish I believe. You will have to excuse frank, not everyone is a P scientist. Flank = back half.

Flank = a full side shot

Get a picture that includes head to tail without any angle on the photo if possible.

I dont think you are going to ever see an S. Brandtii sold as anything else other then that. This is mainly because the area of exportation contains S. Brandtii and does not contain Rhombeus or any other known Serrasalmus for that matter. Although once in a awhile you could get lucky and get an altuvei instead of a rohm.

I think it is a Rhom, Xingu possibly. Some of the other pictures made it appear more compressed, but I think this last one points me to say RHOM. The eyes also appear to be just turning color at this point. He is a bit high backed compared to some smaller rhoms, but I still think that is what you have.

Yeah i could see in a way where it could be identified as spilo cf as here is a pic of my spilo cf, i bought it from nate and this pic is from nates site but the pic does him no justice. I notice a few idd between your fish and mine but either way man nice fish.
