Dont Pinima get really big, really fast? Might want to keep that in mind. Orinos seem to grow pretty slow, wouldnt want your Pinima to grow too fast then one day get a craving for Orino
I got mine at about 3" and they grew pretty fast at that size. At about 4" I added a Peru Mono and a 4" Kelberi. The mono is now approaching 7" and the Orinos about 6". Im sure that has alot to do with feeding though. The Mono is a very aggressive eater, and gets more than his share.
