I just noticed this thread.
I don't think it would be Hoplarchus Psittacus, however if it turns out it is buy it and all they have chances are you won't find them again in a
LFS. The reason I don't think they are is the head slope and mouth area seem wrong to me.
I agree with Nutter, not a firemouth.
Could be a Texas but not pure maybe a hybred of something. Even young Texas' have lots of spangles throughout the body.
I would say some type of Central, a side pic would be great.
I would guess something along the lines of Vieja or a Paratheraps species or a mix of

Possibly a young Paratheraps Hartwegi.
What do they have it listed as, or they aren't sure either.
