Where can I get some GOOD isopods?

[seahorsebill]

Looking to stock my tank with pods before I add fish and want them for my seahorse tank once I get it set up. I have added 400 amphipods a few weeks ago and I added 5820+ copepods. I am looking to add some “GOOD” isopods but I can’t find them for sale anywhere.

reptile stores carry different kinds of isopods, I've never seen them for sale anywhere else
