I tried brine shrimp, fish food and egg, nothing worked. The have all gone to a better place. I ordered another dwarf octopus and will try again, if I am lucky. I am trying to find someone who raises Fiddler crabs or any very small creature. I try pods next time. I also bought several small net boxed to separate the babies next time, again if I am lucky.
The larger Red Sea 350 is cycling now and it should be ready toward the end of October. I hope to get a larger diurnal octopus for the 350.
