Uncycled QT to monitor two clownfish

Since a week in operation, my parameters on Ammonia, Nitrate & Nitrite have been around 0. PH is at 7.9-8.0 and salinity at 1.022.
It is a 10 gallon with a small piece of LR and some PVC tubing, HOB Aqua Clear filter and heater.
How often should I perform water changes and such while holding and monitoring my clownfish for the span of 4 weeks?
MY LFS recommended to cycle my QT with the clownfish but I know it's in a way inhumane.
Also, the larger of the two clowns(female) has been swimming frantically during feeding time and eating only a few munches, whereas the male clown is calm and eats a lot more. This has been my observation for the last day or so.

 

You can try to add some garlic to your food to see if your female will eat more. I don't know what to tell you about your QT though. It sounds like it might already be cycled to me.

 

Throw in some PVC to give the fish something to hide in. To help the cycle along, use a piece of rock from your DT. It has all the biologicals to help your QT water.
