What is this ?

[PowderTang]

May I know what is the orange thingy on the right ?

Is it a worm or anemone ?

Does it eat fish ? There are a few fishes missing and I suspect it eats them. Today ,it almost ate my cow fish....

Please help to ID thanks

It is a tube anemone. (not a true anemone)

its tentacles do pack a punch. If a healthy fish swims into it it will spasm for a few seconds and be ok again.

but if your fish are unhealthy, they will not be strong enough to free themselves from the tube anemone tentacles.

i have personally seen my tube anemones eat my fish.. but many online sources say they do not do that...

also your animal looks really pale.. i don think its healthy..

Oh dear...I guess it has eaten my 2 flame angels which have been missing... Does it eat inverts like slugs and shrimps?

I have no clue if it eats inverts.however if you Google tube anemone there's quite a bit to read.

Were your flame angels small? Less then a an inch?

I wouldn't rule out something else if your inverts are disappearing. .
