and make sure you can feed it. many starfish cannot be kept in closed systems. some live only off of things we can't supplement. some of them are still a mystery as far as diet goes. in other words- we don't know what they eat.
Now I have a reddish(I'm not sure what the name is but will find out) starfish and I'm not feeding it anything. I've had it for about a month and still is moving.
Bristle or serpent starfish are super easy to keep. They eat the left over food that the fish dont get to. I swear they can "taste" food as soon as it hits the water.....they come out of hidding waving their arms around to catch their share of food.
