Pods are hard to see. My chaeto has a bunch if you want some. That said, pod populations wax and wane. If you are not doing anything to build the population it will reach an equilibrium at some point and usually less than we always want. I think feeding them is important if you want to boost things.
This is just an aside story. But I have my a-hole clown in timeout in the sump.
I feed him down there and because of that some food gets into my fuge. Since doing this I've noticed a lot more bugs in there. It may be me, or maybe that extra food in there is fueling their population. You can also look into breeding pods. I think you can feed phyto to boost their numbers. Remember copepods are those TINY specs on the glass. The larger "bugs" although good to have are not "copepods", so look carefully.
Hope this helps.
