I had a question regarding my bubble coral. I noticed yesterday that it just wasn't opening up like it normally does. The bubbles werent' as full. I made mention of it to hubby and told him to me the bubble looked cold. Last week while cleaning the glass he broke our thermometer so there wasn't a quick way to check the temp but he said there was no reason the water temp should be any different. Then last night he tells me he found the water was a couple degrees cooler than it should have been. While doing his tank maintenance he cleaned the heater and didn't realize he had turned the dial down a couple degrees. So now he's put the temp back up to where it was but here it is 16 hours later and the bubble still isn't looking as "full". It is better than yesterday though. I am wondering if the ambient temp of the house could have anything to do with it? Wouldn't the water have warmed back up the 2 degrees it had dropped by now? (it's a 56 gallon) This coral is the only one I picked out and of course, my favorite, and I want to make sure it's doing okay. It also likes to "eat" the red macro algea we have. Hubby has had to pull stalks of algea out of it's mouth quite a few times now. We feed it mysis shrimp periodically, well hubby does.
Here are some pics of the bubble before the temp got altered, as well as a cool pic I took under our new moonlights.
