Colonial hydroids
 

Got some in tank

Anyone know how to get rid of short of taking out the rock

Think I read that the Fluke Tabs killed them too..

They do :)

really?? even the tiny white ones??


huh i may have to look into that ive been going nuts trying to find a way to get rid of mine never thought about fluke tabs.

mine are not the typical brown ones but the tiny white ones .....

Problem is supply of tabs in the country is dwindling :)

Ok. If I did manage to find a fluke tab is ther a ratio per gallon. Are other animals affected buy it. Corals shrimp?

One tab per 100g. Kills cleaner shrimp for sure. All SPS were fine, and all LPS that I have. Did not kill the 2 aptaisia in the tank.

Can you post a pic of it?

FWIW, the few times I had an outbreak, my dwarf angels usually took care of it. (potters angel or flame angels).

You can also try smothering them with epoxy and then removing the epoxy later.

Blowtorch worked pretty good for me on a couple rocks. Be careful if you try it, I read somewhere you can explode the rock if you heat it unevenly. Didn't happen to me but prudence dictates that I repeat the warning that was given to me :)
