what is your latest water reading...??
ammonia-
nitrite-
nitrate-
salinity-
Yes, clown fish are know to hang at the top, next to a heater or any other object that offers them some protection. Once the lights are on it should start moving about a bit. It all sounds like normal behavior.
Still, you need your own test kits. I too am blue/green color blind so I use the Salifert test kits for Nitrite, Nitrate, Calcium, Alk, and Magnesium. I use a Pinpoint monitor for pH and a refractometer for SG. The Salifert test kits have a sharp color change for most tests so it's easy to read the numbers.
I did 2 water changes in the past 4 hours, with my salinity at 2.024. I will be headed to the lfs to get a test kit as soon as the place opens in 1 and a half hours. I have noticed that the little clown is swimming around more with the tank light on. It just floats at the top when the moonlight is on. So far no clamped fins or at the bottom of the tank like I've read about ammonia poisoning.
My clowns didn't eat for a week when I first got them.
Try frozen brine shrimp, make sure they are vitamin enriched, otherwise they will have little to no nutritional value. As for the pellets, if you have the soft kind, it is fairly easy to take a sharp knife and cut them into halves or even quarters if the are big enough. Hikari Marine S pellets should be small enough as is if you can get your hands on them.
