+Lamont Posted May 22, 2014 Share Posted May 22, 2014 I came home yesterday and checked the temperture of my tank, and to my surprise it was sitting at 81 degrees. Everything looked okay except one of my acan colonies. They were huge! Is this a heat issue or are they needing more light? One of the acans seem bigger than a one of my colonies. I posted a pic. Please let me know what you think. Quote Link to comment Share on other sites More sharing options...

Timfish Posted May 23, 2014 Share Posted May 23, 2014 I would say no but I couldn't say that with 100% certainty. Like Bogdan said corals will inflate and deflate sometimes for no clear obvious reason. Quote Link to comment Share on other sites More sharing options...
