Feeding while away

[swill]

Does anyone have any tips to feeding your seahorses while you're away? I'd like to go away for a long weekend and don't want to have to ask someone to come over and feed my seahorses while I'm gone. Is it possible to dry out mysis shrimp so that they will go into an automatic feeder? Once they're dried up they sort of turn into a flake...has anyone tried this?

I know my seahorses will not eat just normal saltwater fish flakes as I already tried that.
