Things You'll Need
Instructions
Observe your Red Sea Star to see what it's eating and what it isn't; it could be eating bacteria from your glass, but shying away from the other food being provided to your tank's inhabitants. As an omnivore, it should be getting nutrients from both sources.
Thaw your food, if frozen.
Use forceps or tweezers to place a piece of thawed food near your red starfish's mouth at the center of its spoke on the bottom. Make sure it's eating the morsel. If you're using flakes, you should be able to determine just by observation if your starfish is accepting this as food.
Feed a red starfish the type of food it enjoys a few times a week on an individual basis. This will ensure that the slow-moving creature will get the nutrients it needs to survive and thrive.
Adjust the amount of food it receives by lengthening or shortening the periods between feedings, depending on how receptive your Red Sea Star is to the food. The amount will vary on size, temperament and available resources.
