I currently have lighting just for fish, a 40 watt T8 and a strip of LED's but am getting a 6 light T5 lamp for free in about a 15 days. Now here is my dilema, the LFS has a beautiful hammerspawn Id love to buy and am wondering.. if I buy him with my current lighting will he die

I have some zoa's and they are thriving if that means anything. I have a nice ledge pretty high in the tank w/ moderate flow, if he could do a week or two with this lighting Id take him. Thoughts?
Cheers!!
