I got some of them on my
LR, and they've been fragmenting and growing. At first I saw only one, and then I began to see them show up with more regularity. I came to this website, as a matter of fact, in my attempt to research what kind of starfish they were and whether they posed a threat to my
lr. I am still left with very little knowledge, as to their species. However, my experience with them has proven that they've been no apparent threat to my
LR. My starfish look like the one on the penny, and have only 5 legs.
Starfish reproduce both sexually and asexually (through fission). And, rarely, does a 5 rayed (legged) starfish develop into a 6 rayed (legged) starfish, of its own accord. (Only those produced at the Chernobyl starfish hatcheries - ok, that was a joke) So, unless this 6 rayed (legged) starfish (above) is in the process of fission, the two starfish are NOT the same, in which case my experience with starfish in my tank MAY NOT be the same, with regard to a
LR threat.
