I have a 2.5 year old 55 gallon mixed reef tank. Lots of coral and all my fish are very healthy. When I think of it, I’ll check my pod population at night with a red light, but it’s been a while. I checked last night, and it seemed to me that the population was kinda low. Normally, I’ll see a ton of pods scurrying along the sand and rock. My question is........is it normal for pods populations to fluctuate? Should I worry about adding pods, or will they bounce back?
