It might seem like it, but generally unfortunately, no. The average adult mandarin eats between 500-1000 pods a today. So figure a 2" sub-adult is somewhere 300/day range. With a typical bottle of pods being around 500 pods, you do the math.
Every situation is unique though. I'm sure if the 24gal was jammed with live rocks, sponges, rubble rock/CC, macro algae, etc, and he was the only pod eater, including shrimp and crabs, there's is certainly that 1-in-1000 outside chance.
