[jonathan543]

pls advice wad kinda bugs are these? notice the green patches on the glass & on the sand juz below the zoos... they're of small greenish patches with really brilliant blue dots covering them... seeing the dots reminds me those on clams... haahaa...

[blueheaven]

Wow I have never seen anything like that before!!!

Do they move??

[LaW]

yeap i never seen anything like those before.

those below looks like small yumas to me.

[jonathan543]

yes they do moved... actually i collected them on 3pcs of rock on the beach... 1st day in my tank all the blue dots are gone... then after 3days the dots are back and some of them actually crawled onto my glass! but u dun actually c them move... think they move when lights are out. dunno if they're parasites but so far they din do any damage to my corals wor....

when i 1st spotted them, i din caught sight of the green colour... it's the blue dots! in the wild they're much much more in brilliant blue dots. think it's my poor water condition ba...

duno wat either

[timzhiquan]

erm. its not really a good idea to introduce unidentified organisms into your reef tank from the wild. u should have checked up on them first.

thanks to venezia's link, most prob those buggers are these...

[LaW]

if its from the ascidiacea class.

then it should be a filter-feeder.

not sure about it too.

[jonathan543]

hmm... i din notice any holes wor... think most prob they rely on light... koz under strong lightning they multiply fast & the blue dots became more vivid... doesn't look anything like a sea squirt to me...

[LaW]

i'm not sure too. it doesnt look like a sea squirt to me too but the link u gave above stated its from the ascidiacea class.

Don't panic.

Yes, they are ascidians. . . commonly known as green scale tunicates.

Harmless but could grow and colonise surrounding areas given the right conditions.

Look appealling with its irredescence blue.

However' not easy to sustain in aquarium though. Need very strong lightings, high flow and continuous nutrient uptake.

You picked it up from the beach . . .recollect the habitat it was anchored on and that will give you an idea of its requirements

cheers

haahaa... cool! but then they're crawling all over my glass... think shift them all to the refugium ba... henry!
