Did you know? When a starfish looses a limb in the wild from a predator trying to eat it, the starfish can grow back its limb. It is common in the wild to see a starfish with 6 or more limbs as two limbs can take the place of the missing one. As with every pet that you have they require care attention; and you must be willing to take this responsibility on before you buy the pet. The average size of the starfish often depends on its species. The blue starfish can grow up to 12 inches on each of its legs. Diet
A starfish needs to be feed daily or weekly depending on the species of starfish. It is important to make sure that when you buy the starfish you ask how often the starfish needs to be feed. Many species of starfish are carnivores and depending on the specific species you can feed a starfish frozen foods.

Also it is a good idea to vary the starfish's diet keep to stay healthy. Housing

If your starfish will be having company with other species of fish it is important to ask the buyer if the starfish will be okay with the inmates. Daily Maintenance
Once your starfish has settled down in its new home make sure that you check the filter daily. Also check the temperature of the water and any other equipment in the tank.
You will also need to change 10-25% of the total volume of water once every two to four weeks. Finally make sure that it is not too crowded in the tank as this may cause the starfish stress and disease.

Reasons why starfish don't need a heart?
Starfish have a well-structured system of tubes that works in lieu of the circulatory system. What passes for this circulatory system uses ocean water instead of blood. A starfish doesn't have a heart, but water running through the arms and feet provides oxygen.
How does a sea star attract a mate?
Sea Stars don't necessarily need a mate to breed, and they don't mate with an individual, or stay with a mate for any length of time. Starfish or Sea Stars, depending on the species can reproduce either sexually or asexually. The most common species are "dioecious", where the genders are separated into male and female individuals. There are some species that are born one gender, only to later change into another gender, as is the case with "Asterina gibbosa". This species is "protandric", they are born male, but later they will become females. Most Starfish use "free-spawning" reproduction techniques. Many experts agree that Sea Stars, use some forms of environmental signs and chemical signals, to gather into groups, or swarms before spawning to increase the odds of fertilization. Then they release their "gametes" into the water where they are fertilized by gametes of the opposite sex. Still other species reproduce by fragmentation. These species will often take advantage of a detachment to develop another individual Sea Star. For more details, please see the sites listed below.
