I've ordered pods from both livecopepod.com and reefs2go, to seed my tank, both were great but I think I liked reeefs2go just for the fact there were a couple different types and they were crawling everywhere. My 2c.
Livecopepods.com has *3* different species of ocean copepods, not Amphipods. All materials are from their 100% aquacultured line are laboratory-reared. You know what your getting with this product, they don't guess! They are also less expensive at 24.99 for 1000+
