We have a few of these in our tank, they seem to drift around and occasionally settle on the bottom or stick onto the glass. This one is about 2mm across, less dangly bits.

They have a 'leg' and 'body' arrangement similar to the Lunar Lander (circa 1969) ie, all feet on the ground, legs pointing upwards, then hinging at the top and then going back down to base of body in the centre, body points upwards. Argh! - that sounds confusing - heres a link for a pic of the lander http://en.wikipedia.org/wiki/Apollo_program

I have seen a bigger one, about 4mm sitting on the sand.

looks like a hydroid medusa to me.

haha not that I know anything about salt water tanks but it looks like a baby jellyfish to me haha. Just a newbies point

looks like a hydroid medusa to me.

either that or a space monster......

No idea

What I want to know is how did you get such a clear photo of it if it is only about 2mm across. Wicked macro function

Pretty cool looking though

its pretty cute looking......

Canon S2 IS

Has super macro that will take a photo of something that touches the lens - none of this 150mm away from the subject stuff.

Oh, and Photoshop, take photos in Superfine and Large format, then crop them in Photoshop so that the critter isn't something like 36,000 pixels to 5 million pixels of water!

In saying that, though the camera is not manual enough for me, just a souped up point and click.... I want a digital SLR!!!!

Finicky bugger aren't you Zev I'd be happy with a camera that can take a photo of something on the lens I'll happily take it when you give it away when you get your DSLR

my mums got the digi SLR by cannon..its wicked

Finicky bugger aren't you Zev

Heh heh, yep!

my mums got the digi SLR by cannon..its wicked

Ooooh Zev, I know where there is a DSLR

either that or a space monster......

I don't want any monsters in my tank!!

I'm having enough trouble with my Maroon trying to 'monster' our new BTA. Poor thing, we've only had it a few days, and the Maroon won't stop wriggling around in it, even when the lights are off - it's almost obscene!

Just as well the Maroon is only little.

Today it must have had enough, after lunch it sucked itself up and hid under a rock, only to have the Maroon in under there sideways still trying to rub itself in it, and yanking at it's tenticles trying to get it out! Now it has gone around the back of the tank and opened up where we can't see it... Grrr

My little anenome had the same problem. :roll: My big mum fire clown did exactly the same thing - basically loved it toooo much. And yeah you are right - I felt a bit like a pervert watching her she seemed to enjoy it so much :oops: :oops:

I took the anenome out and put it in my fuge for a while to let it recover for a bit then replaced it in the main tank as far from the clown as possible. Fortunately the clown has eggs at one end of the tank and doesn't like being too far from them (unlike dad who doesn't leave them at all (bit hen pecked I reckon) so putting the anenome well away gives it a bit of respite. Seems to be doing quite well now, growing and extending nicely and even getting colour back.

You could try moving yours in the tank

:roll: i can see that none of you has any clue!

So what do you think it is Mr know-it-all :lol:

how thick are you? did you read the start?

looks like a hydroid medusa to me.

LOL, my bad............

/me takes note of reading the whole thread first.......... 8)

So is it a good critter, or a bad one?

I don't fancy trying to find them all and fish them out!

quite clearly zev you got it right from the start, nasa made a miniature space ship that landed in your fish tank. phone them up and tell them you know where there top secret molecular atom-ship is and you're holding all crew to ransom until they pay you 1 million dollars...

hmmmm what size marine tank could one set up for $1m US???

LOL, my bad............

thats ok you are not the first who done it!

So is it a good critter, or a bad one?

well not really as it does not harm your normal stock, it may harm eggs or larvae of corals and fish but then so do other corals. the mother stock apparently harms sessile inverts in some books but i never had any probs. as the colony died out soon after the hatching started! :-?

How big do they get?

thats normally it. they will settle soon and start a new colony. i used to have heaps of them but i suspect that my CBB eats them
