PLEASE PLEASE PLEASE
DO NOT buy one of these animals!
THEY WILL DIE.
THEY DO NOT SURVIVE IN AQUARIA
THEY ARE IMPOSSIBLE TO KEEP!!!!!!!!
PLEASE PLEASE PLEASE do not buy one!!!
They require very specific particle sizes of food, which is species specific. They need very large tanks, are nocturnal, and will (with about 99.999% probability) starve to death in the tank. I have only heard of one person ever keeping one relatively successfully. It was a large, mature reef tank, and apparently had some urchins that almost constantly spawned. But this may or may not have related to the keeping of the feather star (Crinoid, aka sea lily). The world's expert on these animals can not keep them in tanks.
PLEASE do not try it!
(I am not above begging!!!)
Do they have a puppy eye begging emoticon??? Insert here --->
Basket stars (not feather stars) are a type of brittlestar. Need equally large tanks, are nocturnal, require specialized attention and will definitely outgrow a 30g tank. I do not recommend them at all either, though the odds of survival are better. Sterling had a true basket star, which now resides at the Shedd aquarium
IMO, both true basket stars and feather stars should be left in the ocean!!!
