Need help IDing little white tree

teranceh · 02/02/2020, 12:53 PM

Longtime lurker, first time serious reefer. Looking to identify these little white tree things as they are starting to appear over the rocks and snails in my tank.

Thanks for your help.

Okay, haven't used a forum in a long time, learning the ropes: the images didn't post. I know my description is useless.

I don't get this forum... I posted a second response with links since the embedded image button didn't work correctly and Chrome shows the reply but Edge and tapatalk do not.

So, the pictures were embedded with the insert image in the original post but are not showing. I posted again with links to imgur and the posts don't even show in edge or tapatalk but show in Chrome. I don't get that.

I'm trying again... with a forum album.

Hydroids.. Looks like digitate variety possibly

Yes. A pest species. Fendbendazole CAN deal with a general infestation, but you will need to do water changes (a number of them, run carbon, and then, once your tank is clear of the med, you will need to beg your LFS for a small number of bristleworms to replenish your population. (Yes, they ARE good for a tank.) See below: there is a safer way that doesn't risk killing off far more life in your tank than you want to lose.

A safer solution if you haven't had them spread onto unmoveable rock is simply to lift the affected rock out and use an eyedropper to hit the affected surface with regular drugstore-strength hydrogen peroxide. THEN RINSE THE ROCK: holding it under a sink tap is just fine for this purpose. Then replace it in your tank. This treatment will absolutely kill any living creature on the rock surface, bacteria, hydroids, clove polyps, xenia, mushrooms, zoas, you name it, BUT the pure oxygen bubbles it may give off once replaced in the tank are capable of burning a fish: (most people don't realize pure oxygen can do that) ---so putting the rock in your sump overnight is a good solution. Or just stand by with a net to scare fish away from it until the bubbles stop. It's a dangerous solution, but it can work on a species that is about to get out of control.
