Ricordia problem perhaps?

[AttackDonut]

Greetings,

I purchased, about a month ago, a live rock with a bunch (~8) green ricordias on them.

They seemed to be doing fine, and then all shriveled up.

About half are back, and have split, so I presumed the shriveling was part of the splitting issue.

However, the others are very small and look like the tossed up their insides, it's white stuff, looks very much like a maze.

I was wondering if this is a bad thing, since the others did it as well prior to splitting, but these last four haven't split and don't look happy...

..suggestions?

The ricordias are in full view of the light, and have been since introduction.

The ones that split are all very large.

Sounds like splitting to me, until you mention
look like the tossed up their insides, it's white stuff,

Mine when they do this, get fairly large, then develop a second or third mouth a few weeks prior to splitting.

Then one day it will shrivel up to nothing, it will be like this for 2-3 days, then all of the sudden the next day I will have 2-3 new individuals.

Since half of them did this, but the other half is taking a long time, it's been like that for 2 weeks now...anyone else confirm how ric's split or what's going on?
