A quick question

How big are Rotifers? I ask because im getting ready to order some golden pearls and i need to know the micron size.

Well, this is directly from Brine Shrimp Direct's website:

Rotifer Size Golden Pearls 100-200 microns (Rotifer / Artemia Replacement)
Artemia Size "1" Golden Pearls 200-300 microns (Artemia Replacement)

I believe either size would work as a replacement for rotifers. Rotifers are about half the size of newly hatched artemia. Saltwater rotifers vary in size from about 130 microns to about 330 microns.

Just out of curiosity, what are you intending to feed with Golden Pearls as a replacement for rotifers? I believe you will have no problems getting corals to accept them but newly hatched fish larvae will usually only accept live food.

Good luck with whatever.

This is from Robert Fenner's site:

Most species are nocturnal suspension feeders. You will want to have timers to cut off your particulate filter(s) during these feeding bouts. Best done by using timers to switch the filter pump motors off for ten to fifteen minutes.

Food material in the wild includes all manner of phyto- and zooplankton and general detritus. In public aquaria, cultured diets of brine shrimp nauplii, copepods and diatoms have proved effective.

Well, it's not a good sign. You have to realize that crinoids are considered next to impossible to keep in home aquaria. They feed constantly in the wild, especially at night. It is just very difficult to feed them properly in a home aquarium.
