Decided to get rid of the FW and make a SW instead, since I live near the coast (somewhat) and make a weekly visit. I’ve been taking bottles of the natural stuff back home in a very slow attempt to fill up the tank. So far it’s less than a quarter full as I can only lug back about an average of 10L a weekend.

Picked up a bunch of floating seaweed just to chuck into the tank to be able to see something other than circulating water. Took a better look at it at home under good light and found a few hitchhikers.

1 Nudibranch - It's white and has reddish stripes with tentacle like protrusions all over it's back. Probably measures only 1.5cm in length. Thought it was some sort of anemone at first but since it changed location after a few hours and keeps moving around guessed it for a sea slug.

2 Brittle Starfish - Both are white and very small too, mostly cling onto the seaweed.

1 Feather Duster Worm – Of the Sabella type, it zips straight back into the tube upon sensing any motion; this filter feeder is only 1cm high even with the animal at feeding station.

Some questions:

What’s a commercially available food source for these creatures? Other than topping up the tank with a new bottle of seawater daily to introduce new plankton and the like, am thinking of chucking in a packet of artemia.

I don’t think I’ll be able to pick up any free coral since the water is bad for that kind of thing here, too much sediment in the water, so will probably pick up a live rock at the shops. Is there anything in particular i should look out for when buying a live rock?

Augh...

An update cos i found a damn Jellyfish in there... Its so small, it's like looking for a contact lens in a bathtub. Don't know if it is the dangerous sort or not yet but doubt so.

Anyone got experience in caring for a Jelly?

don't keep it. they're just trouble.
don'tknow what to feed nudis (they're a pain in A IMO)
in like a food processor, or something similar, smash up some pellet and freed dried food anmd spot feed that to the feather duster.
the stars should forage for food wherever they go. just drop pretty much anything in there for them.
iwouldn't advise using sea water cause as you said it's sedimentatious and they are god knows what else that can find their way into your tank that way. more jellies, disease, pollutants, aptista, and a host of other "goodies" that aren't actually good.
 
Well apart from the initial cloudiness, the sediments do settle overnight in their bottles and i only put in the clear portion. I actually want to have the whole host of god-knows-what flushed out from those pipes because i want to see how the creatures can live in such conditions.

Previously i was accused of keeping too clean a tank, so i've decided to make this one as 'natural' as i can. Besides, it's all free...

So far i've found 2 jellies and there are a ton of little white bugs swimming around for the feather duster and jelly to take care of. The Nudibranch seems to be content wandering around the tuft of seaweed, doesn't travel very far though.

I love nudibranchs, but crawled onto the intake of the filter and killed him.
