sps corals under stress

[kylem]

I recently aquired some coral sps coral frags and put them in my tank. I have good lighting. The corals were originally near the bottom of the tank where I purchased them and they were brown in color. I placed them at the top of my tanks and they seem to be under stress...the polyps are not coming out now and they are turning white. Do I have to much light....what should I do?

Kyle, what kind of lighting do you have them under and if you know what they were under before? Also, what is your photoperiod...did you acclimate them to the current lighting? You can reduce the length of photoperiod to ease them into their new environment. How long have they been in your system?

I'm with Nikki. I would guess light shock. You should always try to acclimate them starting in a similar lighting scheme and slowly migrate them to where you think they wouldbe happy.

I totally agree with Nikki and reedman. SPS corals and especially frags need to be acclimated to everything you do with them. From the previous tank to your, from the previous lighting to yours. You need to start them low and slowly as they acclimate raise them til you see they are happy and hopefully doing what you want. Which would be coloring up and polyp extension.

The fact you are seeing white is probably lighting shock and they may not be able to make it back. What I would do immediately is place these new frags completely down in the sand and see if they will try to make it. When you see new tissue regenerating only then would I very slowly try to start to move them up.

Goos luck....

Kyle,
I agree with people above very much. I am wondering if you have too much direct current or other corals close by affecting frags. Remember the underwater battle ground with corals fighting for territory. Its fun to learn what type of environment that coral came from and see how well you can mimick it. When people say white ends on coral it confuses me at times. Sometimes corals growth can be white.

Good luck,
Ed
