Hammer showing long tentacles

[ssunthar]

Hi experts, my rose gold hammer started whipping out long tentacles (as long as 10inches) last few days... not very sure why...

Anthing I should be doing.. i am worried it will start stinging other corals nearby. Thanks.

Is it possible I could get some growth like this on a piece of petrified wood in my long island sound tank?

Those are sweepers, defense mechanism. Nothing you can do but make room

My splatter branching hammer has been doing the same thing ever since it started splitting. I suspect it's reaching for turf. It stung the crap out of one of my micromussas (since moved). It's pretty close to a bi colored hammer and they seem to be OK together.

In my experience it is an offensive mechanism... I have had a few that were just plain mean.

It’s possible it’s being triggered by the frogspawn behind it. I don’t think those will harm other hammers but be weary if you notice them getting close to any other kind of coral

He's mad. There's something to close that he is trying to sting. I put an acan near one thinking time was safe. It was up stream but the yellow hammer zapped it. Maybe a short move for him. I just moves a bunch of hammers that we're fine till the grew. Then they looked mad all the time. Best wishes.

Moved/isolated him from the rest, still seeing his sweepers out.

Will keep an eye. Thanks.

From time to time it happens. I've changed flow before and all the hammers and torches went crazy for a few days. Since you're original post I've had to move a splatter hammer from a yellow for the same issue. Keep you water in good shape and enjoy your hammer. He looks good.

A quick update... after I moved the hammer it was still showing the sweepers for a few more days. Its been a while and I am not seeing the sweepers any more. Thanks all for the help.
