It's hard to rate this place without comparing it to New World. Selection wise, they certainly don't have as much available in store, but they are more than willing to order anything you may require if you give them a few days. The prices on everything are significantly cheaper than New World, and though they don't have as much tank space or selection, they are a better bet for rare and unusual stuff. I've seen everything from bitterlings to numerous rare cyprinids and characins there. Also some really nice ranchu goldfish from time to time. They also have a buy 2 get 1 free policy which reduces prices even more. Word of warning though, their stock gets pretty run down between orders so schedule the beginning of the week for fish, and the end for plants. The staff at Pacific is crazy friendly, and far more helpful than NWA's. Their planted tank is also a sight to behold. Now for the detractions: The store isn't particularly clean, and they could stay on top of tank hygiene a bit better. Also, they can be ht or miss in terms of selection, because the store seems to get quite barren between shipments. Other than that though, these guys are awesome.
Pros: Many planted tank experts on staff
Cons: selection sometimes a bit thin
