So what is the best way to grow amphipods etc... as a food source for the display within a refugium? Is it best to have live rock rubble, I've seen them in my chaeto. Any ideas?
This product has worked for me before...

If you can not find it I might be able to pick some up to you and bring it to the swap.
I've seen that around. Thanks. Just wondering more about conditions that will favor them reproducing, having food, and places to live and hide.
Here you go.
Or umm... you could ask ME... the Reef Nutrition representative on BAR, they guy that wrote that text and who will be updating it soon.
3/4 of the Bay Area LFS stock and carry RN... not to mention we are a local company and routinely donate to BAR's functionsas we'll be doing for the swap.... not to mention I'll be at the swap.
I've used triggerpods a couple of times. For places that they can reproduce you just need somewhere of peace persay. Don't want anyone who loves to chomp down on them. So a refugium is ideal place.
And you'll need to do what I said above about feeding both them and their predators (mysids & amphipods). FWIW it's Tigger-Pods

Wikipedia is more right than google, unless you google a wiki page and then the world assplodes.
Food supply is the greatest limiting factor.
Amphipods and mysids prey upon copedods so keeping them fed will help increase copepods.
Copepods are typically limited by a phytoplankton source, although they can feed on other stuff. Phyto is the best for getting larger numbers though.
For Amphipods and Mysids I feed Oyster-Feast and Roti-Feast to my fuge (small amounts) and for the copepods I feed Phyto-Feast.
Some rubble or cheato is fine, as is a course sponge.
