Euphyllia glabrescens health signs

Hello all

so it seems i have fallen to the temptation of getting a hard coral.....and im glad i did!

i got me self a nice green torch coral and have been doing extensive reading on it so as to give it the happiest home possible.

now aside having given it ample rooms to "sway" at night without it zaping any other of my corals, i had a few questions for you guys.

firstly i have 2 t5 light rails composed of 2 day light and 2 night lights, they are only ever all on together about 3 hours (1.5 h in the morning and 1.5 at night) the rest of the day (from 10-8pm) only the 2 day lights are on. this being said i placed my torchy just under mid tank level, i have read it is best to place it on the sand bed but i dont have good water flow there and where she is now she gets a PERFECT medium diffused water flow.
so yea my question is this; i fear she might be getting to much or to little light and if she is i dont know what the symptoms are, do any of you have an experience concerning a color change when a torch is over or under exposed?

i have read Zoas tend to turn brown if the light is not right will the torch do the same? will stay in hiding to try and protect its self from to much light?

i have had her for a couple days now and she has a healthy intense bright green to her.

Also i have touched her a few times with my hands to move her and have not gotten stung, apparently the skin on your hand can handle her venom but i have also read that a coral that does not sting is an unhealthy coral (i will try touching it with the bottom of my arm to see what happens....yes i am a masochist)

anyway please share with me your endless knowledge i am most eager to learn.

thank you and kind regards

Hi, Jeff-

Most Euphyllia species will slowly shrink and recede into their skeleton if not receiving enough light; OTOH, they generally bleach or lose color with too much. They are fairly adaptable however, and will thrive just fine under a particular range of lighting.

Also, most stony corals do not sting with their photosynthetic polyps, only with their nighttime feeder/sweeper tentacles.

Hope this helps.

 

Also, the oils in your skin are very bad for the coral, very. Try to avoid touching the fleshy part.

thx guys will keep an eye on her

 

right so i moved her further up closer to the light i was not happy at all at the length of her tentacles and they way she moved, i placed her in a corner where there is less current and after a couple days she looks much much better, however wanted to hear what you guys thought.

the ones they have at the LFS seem to have a lot longer tentacles and are less bright green. for the record im running 4 t5 2 days and 2 nights.
