Hydroids - "CURE!"

I have for years been "blessed" with several colonies of brown polyp hydroids. They have pretty well stayed put over time, and spread rather slowly so I have just learned to live with them.

Only way I have ever heard of controlling them was pulling out rock and scraping off.

I would often scrape off bunches on overflows when siphoning.

Couple of weeks ago:

Today!

​

There are only two possible explanations.


(1) Month or so I added some peppermint shrimp to tank.

or:

(2) Recently I have had a CC star wandering around in tank that my Harlequins have shown no interest in.

Am not sure due to which...but the hydroid colonies have been decimated. ;D

 

V for Vicotry BTW, even with your "blessed hydroids" your tank is amazing !

 

that is #$^%ing great.i never had that issue.

Will know for sure which (shrimp or starfish), as the star is coming out if the Harlequins do not get it soon.

Will see if hydroids grow back.

Peppermints are known to eat hydroids. But its luck of the draw just like with anything else.

 

my credit would go to the peppermint shrimp, i have seen first hand, my pep. shrimp went strait for them the second i droped him in, within 18 hrs he ate my only 2 aptasia, and like half my colony of hydroids then he dropped dead for no reason, proly due to acclimation. plus side, i havent seen the aptasia since.
