Any one keep what are referred to as Red Hawaiian Lobsters? Really are beautifully colored. I feed the one I have fresh cooked and frozen cooked shrimp and prawns.
I have one. It hides most of the time, you have to look with a flashlight at night to see it. I leave cocktail shrimp for it or feed it with s stick. In the spot where it normally is there appears to be quite a few snail shells. I think the random unwary snail that ends up in its space becomes food.
