re: crinoids in aquaria

[N.Monks@xxxxxxxxx (Neale Monks)]

Folks,

Stalkless crinoids are quite widely kept in domestic marine aquaria. They
are (as far as I know) all tropical species mostly collected from South
East Asian reefs. Genera _Himerometra_ and _Lamprometra_ are reportedly the
dominant taxa.

In captivity they do reasonably well provided they have adequate food and
fishes are not kept with them. They are well known for their habit of
climbing in front of the filter outlet, where the current is strongest, and
losing arms if the current is too strong. They also appear to be nocturnal,
ambling into shady nooks by day. They are surprisingly mobile.

They are all pretty small animals, no more than 20 cms in diameter.

All the best,

Neale.
