STPs haven't been in the pet trade for long enough to have any concrete evidence, but Borneos are generally a bit smaller and more docile than bloods. Husbandry is the same.

I've got a Borneo, love him to death. He's hissed, whipped, and can be a pain to handle, but no tags yet.

Got mine from Keith at The Blood Line. http://www.thebloodline.net/ Highly recommend it. I've also heard wonders about Kara.
