Fast Breathing

Could it be an oxygen issue? Are you getting enough oxygen exchange? Maybe point a power head at the surface....

Sounds like your are having a diurnal fluctuation in oxygen. A lot during the day, and depleted at night...Is there a lot of algae in the tank?...Like mike suggested, point a powerhead at the the surface...perhaps even add another, or airstones.....

I really think it is an oxygen issue if they appear okay in the day, and stress at night.

I think the problem was low oxygen. I added an air stone and that seemed to work well. I find it weird that this problem didn't come up sooner. Either way I'm glad to have it fixed. Thank you to everyone that added there input.

Nice to see a good ending.

good deal. Thank you for posting as you did. It is very trying to help people with any situation in a SW tank without all of the info. Welcome to MAAST, if you haven't been welcomed already.

What is the total amount of flow in your tank? You may want to stop in at one of our sponsor stores and ask about a sump, and some filter socks. Way easier to deal with than what you have imo.
