serpant star help

my serpant star is loosing his legs. it started out with just the tips and has progressed up the legs so that now he has about 1 inch long legs all the way around. What is causing this? my parameters are in great shape. there is plenty of places to hide and plenty of food around for him to scavenge. any input would be helpful.

 

What is your nitrate and salinity? Is your salinity stable? How often do you add top off water and how much do you add at a time. How many gallons is your tank.

A common problem with star fish is low salinity or a changing salinity.

salinity is 1.025 and stays pretty much right there. i have a 75 gallon tank and i do a 10 gal water change a week.

 

also i shoud add i have two other starfish that are doing well. a sand sifter and i am not sure what the other is called but its big and green with dark spots that cruises the tank constantly.

 

I just read yesterday that a serpent star can lose its legs and the regenerate rather quickly.

 

Acemow what was the reason?

 

Yes they can.

They can regenerate if what ever caused the damage in the first place is gone, they will normally come back pretty quickly.

What else do you have in the tank?

 

What livestock do you have? My Coral Beauty has nipped my serpent before. The legs reginerate super fast though...so something must be hurting it constantly if its legs are going away rather than coming back.

 

Electric blue hermit crab, BTA, another star(he is alot bigger and don't go under the rocks) turbo snails and a sea urchin, two P clowns a yellow tailed damsel and a lawnmower blenny.
