Help to ID this thing

[vdfne]

Hi, i notice there's a white hole on my touch( if i got the name correct). There's a thing inside it. It only shows it's feeler coming in and out of the hole. i'hv tried to take the whole tg out , soak it in tap water n leaving it out of water awhile, hoping that 'the thing' will come out but failed..... Tired using a pin to poke it but it was dam hard, can say as hard as a stone...

Anyone can help to ID this? Hope it's not sometg bad.... Since intro it to the tank, 2 fish have been missing... Feeling dam uneasy now

Looks like some kind of tubeworm.... possibly a vermatid. should be harmless. Do you see stringy threads/webs coming out from it?

Are the 'feelers' like feathers or worm-like?

The feelers are moe of like feathers, also white in colour, very thiny.

Hope it's not the cause of my missing fish.

Does it disturd the touch also? Cause that part of the touch doesnt seems to open up now.

I don't think you should worry excessively. That looks too small to be even of any threat to fishes. A worm that builds a tube doesn't leave it.

Tnk barnacle & At.
