Theres a lot of newish info on how we have been feeding bandensis. All can be found in this forum.
-Live mysids is necessary for the first 0-1.5 months. You dont necessarily need to breed them, just keep them alive long enough to be consumed by your cuttles.
-At around 1 month, I would suggest trying to train them to eat frozen mysid.
-At 1.5 months or so, its a good idea to move up to shore shrimp. Some of your cuttles may have learned to eat frozen already, but continue with mixing live shore shrimp with some frozen ones until all seem to readily take frozen.
-After this, I would suggest looking at bait shops or other areas for 1-3 inch size frozen shrimp. In the SF bay area, our bait shops have grass shrimp, which are perfect, but may not be available in other states.
