Species details: Spinachia spinachia

I originally had three, all from Falmouth (Cornwall), but only one grasped the concept of frozen food. As the other two only accepted live food even after a month, they got to go back to sea. I like this species for its uniquely rigid posture, a bit like a horizontal seahorse, but feeding is really a problem. Even the one that accepts frozen food needs many feeds a day, presumably because the body is too thin to hold a lot of food in the stomach. Apart from that, this peaceful species seems hardy as long as temperatures are kept down.
