I was curious to know how safe it would be to house a tiger tail cucumber with a pair of cuttles? The only thing I could find out is they generally leave echinoderms alone. I remember having a conversation with someone locally and they mentioned cuttles will eat worms, so I was a little worried that it may get mistaken for food. The cucumber is about a foot long. And would the death of the cucumber kill the cuttlefish? I know a dead cucumber can easily kill a tank full of fish.
