I would be more than happy to start selling fiddlers to you guys for as cheap as possible, but i dont know where to get info on shipping costs and other shipping info. i'm going to ask the local bait shops where they get their fiddlers too.
You may want to think about adding some variety to your octopus's diet. You can try scallops (fresh or frozen; can be bought from a seafood market or possibly a local grocer), or frozen krill or silversides from your LFS will work fine. Variety is good, even though the alternative food may not be the healthiest for the octo (I.E. silversides), it will keep your octo entertained with it's food. Snails, hermits, and live shrimp/crabs are also good alternatives that can live in the tank until eaten. The best part is watching them catch and eat live food!
