Head uut aastat kõigile!

Leidsin imeliku olevuse ringi roomamas. Olin ka umbes nädal tagasi teda näinud, siis oli ta tunduvalt väiksem ja liikus vaevaliselt, nii et oli raske aru saada, kas on elusolend või mingi liiva sees olev kojatükk. Nüüd liikus päris nobedasti, umbes toll minutis - algul Sarcophytoni jalal, siis liival ja lõpuks kadus kivide vahele. Liigub selle pikema haru suunaliselt.

Kas võiks tegu olla mingi meritähe lapsukesega?

Albert,

Please forgive if I didn't understood you correctly but are you asking what it is?

It is a common hitchhiker on live rock, a Asterina sp. seastar. In your pictures you can see very well their asexual method of multiplying: they drop some of their "feet" that then grow to complete animal.

Most people consider them harmless although there seems to be a few coral eating species.

Absolutely correct.

Thanks, Tatu! Yes, it seems to be one of those (bad?) guys. I'm now confused if I should remove it from tank? The people at GARF state that all species are potentially dangerous to corals. Yet it bothers me that they can multiply very quickly. Should I isolate him somehow and keep my eye on it?

albert,

I would let it stay. Like most sea stars they probably are eating small micro-organisms together with detritus from the rocks but do little real damage to your captive reef.

It seems that the ones that eat corals are extremely rare and if you had one of those you would have noticed already They will kill your corals quite fast...

OK, peace with him... Anyway, I don't have any delicious SPS coral that he might like for dinner.

I saw him again moving around on the rock, it looks like he is really more interested for algae than corals

P.S. I posted this ID request to another forum and results there were almost the same.

Hei Albert,

Tõenäoliselt on see meretäht Asterina sp., nagu Tatu pakub. Tõsi, ta on Sul erakordselt ebasümmeetriline. Mul on ka mõned võrsete akvaariumis, ilmselt elavad vaikselt paljudel. Mingeil tingimusel võivad ka kontrollimatult ja probleeme tekitavalt vohama hakata.

Tervitades,
Sassa

Thank you guys for very useful information

Found it today crawling on the glass. Here're the close-ups taken with my new camera


This one is taken using flash. Because the objective was about 2 cm from it the light is actually coming from the backside.


Here it is as it really looks like Very nice guy indeed. There is at least six of them in the tank now and more is coming, I guess

Tere,

lahedaid kujusid leiad oma akvaariumist.
Huvitavad on tal need allpool nähtavad tundlad.


Sain hiljuti juurde elusat kivi ja avastasin üks öö
ühe kivi pealt välja sirutamas 2 sarnaste tunnaldega looma.
Minu omadel on sellised ümmargused peaaegu läbipaistvad kehad
mille ümber on täpselt samasugused tundlad ringis. Neid tundlaid
nad aegajalt liigutavat nagu püüaksid toitu. Ei tea kas mul võib tegemist olla mingisuguste hüdradega, anemoonide moodi nad ei paista olevat.
Üritan neist varsti pildi võtta.

Tervitades
