I have bought from IPSF twice, both mix and match. The quantities are somewhat small, but everything worked out very well. The pods
were a little skimpy in numbers, but that seems to be the case with any order from anywhere. Most of the stuff from my fix order went into the sand has not been seen since, but all of my levels are pegged at 0 so I am not questioning it. My last order was for all the Tang Heaven and a pod breeding kit so I can start growing food for my tang and my mandarin. I got the Anthelia Polyps and was very disappointed in the size of them. They were about 1/2", but if they grow I will be happy. I have found a place online that sells Amphipods and Copepods in large and small culture. I have not tried LFSCultures.com, but I am going to this week to see if the quantities are better. I will post on it later. Hope that is a little help.
