closed polyps

I have a button polyp frag that I have had for about two months. For the last couple of days a few of them have been closed while others are open. What is happening? It sits at the top of the tank.

When polyps close suddenly it could be a warning sign that your water quality is declining. Check your salinity and all other parameters. Check if your bulbs need replacement or the lid is dirty. Make sure there is no physical damage from any tankmates. If there is still nothing apparent just give them time, polyps are usually one of the most hardy corals out there.

If some are open I would not worry.. Mine do this from time to time not sure why? In fact my volley ball size button rock 3/4 of it was closed all day yesterday?? Today all is fine. Maybe they are reproducing? Are there other corals in the tank, if so how are they. If they are fine then I would just wait and see. Checking the water is not a bad idea..

Honestly I haven't done any water changes. I feel unless it is necessary the water that is in there is the best water. I add a few gallons of fresh water a week due to evaporation so until something happens to my parameters(like now) I don't think I'll do water changes on a scheduled basis. This is just me though.

You should do regular water changes, to keep these levels down. The trace elements in the fresh salt water is what will help your corals take off. I am just learning this. Also I believe corals are real picky when it comes to high Nitrates.

You really need to do water changes in order to be successful, especially with corals. Once you get in a bad habit it will be hard to break.
