Here is a good article:

Typically, the linckia species die in captivity, there are exceptions, but I'd stay away from them. The Fromia stars are the hardiest aside from serpents and brittles. Tank needs to be matured, probably at least 75 gallons with ample live rock and very stable prams. These guys need very careful acclimation in regards to salinity. They are also sensitive to nitrate.
My new tank seems stable but I don't trust it to be honest. I just feel like its going to cycle. My chems all seem fine but the PH has been swinging a bit more than I like from morning till around dinner. I'm seeing a drop from 8.1/8.2 into the low 7's. I added some kalkwasser to my ato, and started dosing a little to bring it up mid day trying to get it to not drop so far. My ATO uses a pump that pretty much just dumps about a quarter gallon in when the float tells it to. I'm considering moving to a much slower pump and raising the amount of kalkwasser. Currently I am mixing 1 TBS to each gallon of RODI with a power-head to keep it moving all the time. I may work up to 2x or more over the next few weeks to see if that helps. I'm not worried about the swing at night, I just want to level out as many of the minor stability problems.
That being said, I may need to wait on a sea star. I'm already holding off on my surgeonfish stocking for about another month so I can get a really good stable flow pattern and macro system in the new rockwork. Flow is proving to be a challenge for me. finding a good flow that helps the LPS,SPS, inverts and nems plus no dead spots without being just way to much will take me some time. That Jeabo WP40 is awesome, I'm running it on pulse at 33% with my MP10 on lagoon at about 40% and most things seem happy.
So far my list is.
lemon peel angelfish
Purple tang
squaretail tang
Female Hoeven's wrasse (already have the male)
orange-back wrasse
sri lanka yellow wrasse (already have her)
six-line (already have her)
snowflake clown (got her) they have paired
blood orange clown (got him)
Maybe's
marble sea star
sea apple
some fire cucumbers
ordering
a good amount of Hawaiian opi glass shrimp to hide in the rocks to be hunted.
cop/amp's to help keep up with the wrasses
one of those big macro packs with the reds/blues/yellow macro to stuff in the rock pile and sump.
I'm going to go get some pie and think about this

.
any advice or if you see a newbie mistake in the works just let me know what I need to reconsider
