Welcome... how long ago did you buy the coral? How did you acclimate? What are water parameters? Lighting? How long has tank been set up? More information will maybe get more responses...

Water parameters: pH 8-8.2, ammonia 0 nitrite 0 nitrate 20-40. Have had tank for 6 weeks. Cycled it. Water changes when nitrate goes above 20. Other parameters never exceed limits. Feed once a day. Coral has been in the tank for about 2-3weeks.

My guess would be the tank is no stable enough yet,meaning nitrates at 40 will irritate corals ..I would try to get the nitrates to 0

I wouldn't wait for the nitrates to go up. You'll want to do your water changes on a schedule. I do about at 10-20 percent change every week on my nano. And every other week on my 125 and my nitrates stay around zero to maybe 5

What lighting do you have over the tank? What fish do you have other than the clown?

Alright ill try upping the water changes. My tank is the new fluval, I don't know what the lighting is on it but I asked what coral would b suited to that lighting and that's wat they told me. I got the clown an orange tang and a blue spotted puffer. A few people have said is the puffer nibbling at the coral but I watch him quite a bit n never see him biting it. My other corals seem to be doing fine

What size tank is it? The bioload could be on the heavy side hence the suggestion to do weekly water changes. Could also be the lighting if its the tank I'm thinking of I don't belive the lights are strong enough for coral. Some more info would be great.

Good evening... I'm confident it's a combination of water quality and light intensity. The older your tank, the better, and preferably the equation for lighting is 3-4watts per gallon provided you have the right light spectrums. Fluvals are not known as great saltwater nano tanks.
