Soft, Blue Openings, Filters, And Spits Out Sand?

[PaperArrow]

Its been in my tank for a couple of weeks, but it has grown on me, and i would like to know what it is if anybody could point me in the right direction. its small and i would realy like to encourage it to grow.

The brown and blue burger shaped thing, under the shrooms and polyp type things.. i took a few pics to show it filtering.

Any ideas?

Oh if anybody remembers the coral hermit hitchhiker that came with my mushrooms....today it moulted!

I'm not sure on the blue things... possibly a sea sponge?

 

[rictheredneck]

dont thinks a blue sponge if its opening and closing.

looks a lil like two things neither of them i know anything about - when it open it sorta looks like a tunicate dunno if they open and close and sorta looks like barnacles but your guess is as good as mine

Thanks guys looking online its definatley a tunicate, two openings are for in flow and out flow.
would a tunicate (or any creature in general) only have this bright blue (my photos look quite washed out) colouration on the inlet out let in order to utilise the light somhow? or would it be to entice somthing in?

Man... you got loads of goodies in your live rock. I could virtually guarantee if I bought LR, I'd get hitchikers like mantis shrimp, fireworms or an unexploded Japanese torpedo from the Indo-Pacific rim

 

[PaperArrow]

lmao! However ive also picked up tonnes of bristleworms, bubble algae, aiptasia, and manjano (sp)!

I've got a load of bristleworms and I'm virtually positive that I have a couple of fireworms too, from looking at photos. I've got a peppermint shrimp coming next week to deal with the aiptasia I've noticed making a reappearance.

Where did you get your LR from btw?

 

[PaperArrow]

I got my rock from dobbies bletchely and japanese koi in henlow - the rock form dobbies came with the bubble algae and aiptasia, the stuff from henlow with the mjano and bristle worm ....so now ive got the full set to deal with!

So far ive just let the pests do the thing, somthing else to look at ,but its getting to that stage where i am going to have to do somthing with them before they takeover. looks like emerald crab is next on the list for me, (if i can convince my self the ones i have seen for sale are not indeed bloody teddybear crabs.)

my rock has virtually no pests, except hydroids but there not that bad (i'll still get rid of them though) i got bristleworms but im keeping those. And best of all i got a mushroom coral
