I've got a 20 gallon refugium, 4-5 " live sand with at least 3 different variations of calupra,It's been running for a little over a month now. The calupra is growing great. There is 1 red leg hermit crab (who knows wehre he came from) and a turbo snail that tried to escape to the refugium only to discover he was too large to fit down the overflow, We removed him from the overflow and he sat motionless in my tank for 24+ hours (thought he was dead) placed him in the refuguim for the crab to clean up and use for a "new home". After 8 hours or so I noticed his shell had moved, okay, so the hermit is eating his dinner on the run,- after 24 hours, the snail deciced to resume life and has remained in the refugium doing snail things. <br />What do you have in your refugium? What would you like to have in there? Thanks! <img src="graemlins/beerchug.gif" border="0" alt="[Cheers]" />

Hey Madamglass!<br />I have about 3 or 4 different types of calurpa and and some sort of funky micro algae growing in mine. Lots of 'pods. I also have a couple pieces of live-rock that I didn't want in the display. There are 3 each of: Cerith Snails, Astrea Snails, Margarita. I did this because one of these has been laying eggs in the main tank, and I figure the fish are eating them. If nothing else, they will provide food for the tank.<br />I would like to try a sprig of dictyota in there, but now I am not sure I am providing enough light for it.

I'd add some shrimp, peppermints would be preferrable, but any that will propagate will be ok, not for any clean up reason, just that they provide instant plankton about once a month... They are hermaphroditic, so you don't need to worry about getting a male and a female... I'd add some halameda and gradually remove the caularpa spp, just because the caulerpa spp may go sexual eventually. Also put a lot of your live rock off the substrate by about 1 cm, this allows a great place for the benthic critters/'pods, etc to reproduce, adding another nutritional source to your refugium. Also, don't be concerned with a little algal growth, this will feed the copepods/snails, etc, but if it gets out of control, just export it out (to file 13...) I find that my refugium is probably as entertaining as my display, and may become a home for Crabzilla soon.

I got rid of my Caulerpa racemosa (grape caulerpa) when it went sexual TWICE in 2 weeks <img src="frown.gif" border="0"> but I've got a ton of feather caulerpa that I prune and share regularly. Started with a sprig from work and another sprig from a "package" of tank raised specimens I got back in February. The caulerpa long outlived the livestock <img src="rolleyes.gif" border="0"> . I've also got a sprig or two of Halimeda sp. that I pruned out of a tank I maintain, where it grows profusely.

I had thrown a few grass shrimps that we caught in FL in there, haven't seen 'em lately but the caulerpa is thick so they could be hiding. Other than that, just copepods, amphipods, and gammarus shrimp own the joint...that and some worms and mini brittle stars that inhabit the live sand.

I agree.....the 'fuge is just as entertaining as the main tank!
