First coral zoos in tank

Ok i have not yet mastered taking pics of tank yet as you can see. I purchased a rock with zoons on it a couple of days ago. Once i got them home i acclamated them just like my lfs said to. they opened up cool my problem is whith the lights on the open right up but at night when i shut the lights off the y close up. I dont believe it it suppose to do that. I have coraline growing on the glass and on the br. Here are some pics like i said they are hard to make out.

 

Perfectly normal behavior for zoanthids. Congrats on the new addition!

 

This is normal operating mode for most corals seabass. There are types of nocturnal corals, but as far as I know most zoa's don't fall into that group.

 

Thanks i was worried about them being first corals in tanks now i can sleep better..

 

They will close up when the light goes off, perfectly normal for allot of corals, but go look at your tank a couple hours after lights out and some of them might be open... At least mine do that...

Every time I see a post about new zoos I am compelled to point out that they can be dangerous. I wasn't told this and to my dismay most LFSs don't know. DO NOT TOUCH THEM W/O GLOVES. I won't go on and on about this but... a little reading on paleotoxin and you will learn what I am talking about. I am not the zoo police - just a concerned reefer... be careful.
Happy reefing.

 

I have touched my zoo's many times will no ill effects......yet.

 

maybe it only affects some people... like poison ivy or poison oak.. i know some people that can roll around naked in the stuff, and it not bother them a bit, but i can't even get close to it without having a breakout... but i guess its a good idea to wear gloves anyway, i mean, don't ALL corals have some sort of venom/stinging cells to some extent? i just finished reading about zoas/zoos (whats the diff?) and handling them.. deadly if consumed, or if it enters the blood stream, but if it gets on the skin, it mentioned something about just "local" something or other.. i took it as just local, minor skinn irratation..
