Brittlestars (same as serpents stars) are simply the greatest animals you can possible put in a tank.
Why anyone would keep anything else, I don't know.
I am not in any way biased. Slightly insane (since I have studied these beasts for 10+ years), but still functional.
STAY THEE AWAY FROM THE GREEN
I would say most people do not have trouble, but some do, so why risk it? They are known predators in the wild, so are not doing anything unnatural.
The red serpent is beautiful, but very delicate.
For all of these guys, use a slow drip acclimation, at least 4+ hours.
Spot feed all brittle/serpent stars, even though they are good at scavenging for things. Anything meaty will do, from silversides, squid and krill to something simply like shrimp pellets, etc.
I don't know that they are "good" for a tank, but they are very very common on coral reefs. You probably already have quite a few if you have LR.
