Single clownfish not eating.
My 75 gallon tank has been set up for about a month with a single Ocellaris Clown. The fish has been in it about 2 weeks or so, I bought it, the week before Memorial day. It was fed Mysis shrimp twice a day and ate voraciously until a couple of days ago when it would spit the mysis out, now it won't even take the food. It just lets it float by. I went to Petsmart to buy some Algae sheets but my wife said "Don't buy anything that doesn't say 'clownfish' on it" so I bought and some marine omnivore "gel" food. The fish spits the gel out as well as the Hikari small pellets I had on hand. I suspect the diet is lacking something (algae probably), or maybe that one cube of shrimp is bad. It doesn't seem be as actively swimming as before either. I haven't noticed any external spots on the fish and coloration seems normal. I've been concerned before when it did something different but it always ate so I figured it was normal behaviour, but not eating is concerning me.
Tank levels seem fine with Ammonia 0, Nitrite 0, Nitrate 5ppm or so. Ammonia has never been above 0, nitrite recently dropped from 0.25 to 0. Tank has 50 lbs of dry rock, 10 lbs live rock, and 20lbs of "live sand" from Petsmart, 30lbs of aragonite. There are diatoms and algae. Lighting is a coralife 50/50 34 watt. Filter is live rock, and an Eheim canister that is really just pushing water with just the filter pads and no media in it. 2 koralia Nano 425's keep the water moving as well.
Thanks for your help.
