starfish ?

[keish24]

are the red linkia or the orange linkia stars easier to keep then the blue linkia. i have seen a lot of info on here that say the blue linkia stars usually starve to death but i was just wondering if the red and the orange species are the same way.

i have a 55 gal tank with about 75lbs of live rock btw.

Neither, IMO, are suitable for your tank. All reef safe seastars (Linckia and Fromia) are very sensitive - they require mature pristine reef tanks with loads of high quality porouse live rock.
How old is your tank?
What are your specific tank parameters?
IMO, you do not have enough live rock to sustain those stars long term. Some may argue that the orange, in particular, is hardier than the blue but that is exceedingly relative. They are all very delicate.
