shifty my red starfishes fingertips?

[mandarinman]

Shifty has fingertips that tend to fray and shorten. every time i see it happen i give a squirt of iodide at him and his area and it comes right for a few days and heals a little shorter. he likes to sit at the top of the tank and stick his fingers out slightly. really confuses me.

i have seen this behavious befor alot of star fish sit at the top of the tank with 1 or 2 legs floating just under the surface.

They may be catching the surface "scum"?

Turns out that starfish fingers fray if they experience salinity fluctuations even if it is slight. i dis my waterchange a little faster than normal yesterday and as long as my waterchange water is 1.024-5 i dont worry. now i know it must be exactly the same! If adjusting salinity do it superrrrrrrr ssslllooowwwww!
