We have a niger trigger, clown trigger, porcupine puffer, hermit crabs and some damsels all in a 55 gallon tank with some live rock and coral. All get along amazingly well.
For two days now, all have been experiencing heavy breathing, the puffer has been lying on the bottom of the tank, which he never does, and his coat looked almost as if it was rotting off for a bit yesterday (although it wasn't and got better after a water change.)
the nitrate level was a bit high so we did a water change and the fish started moving around again for a little while. But all three are very very sick and at the moment, the niger trigger can barely even move and is lying on the bottom of the tank: still breathing but heavily.
the tests all show a normal ph,ammonia and saline level (although the nitrate level is a tiny bit above normal, but nothing dangerous) and the temperature is normal.
Has anyone ever heard of or experienced anything like this?
it's probably a chemical agent that has contaminated the tank but we've done about five water changes in the past few days just to keep the fish breathing, so what else can we do?
if you have any ideas, please let me know.
thank you!

What type of filtration do you have? If you think some sort of chemical agent may have entered the tank, you may wanna try some carbon. If you dont allrdy have some in your tank. :D

I would check if your tank is getting any air. Do you have an air pump? If your tank isn't getting air, this would be the reason when you changed water, and added freshly oxenigated water, the fish statred moving....

It sounds like the fish aren't getting enough oxygen in the tank. Did the puffer turn a yellowish color? Try putting a pump with an air line at the bottom just for some added oxygen and circulation. Make sure your filters are flowing well. GOOD LUCK!! I hope they make it.
