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.
