Saddleback anemonefish (Amphiprion polymnus) are obsessive about tending to their eggs. There are many photographs showing these fish taking care of the next generation, but somehow, a single image doesn't quite convey how much energy these devoted piscines invest in ensuring healthy offspring.
The eggs are the bright orange patch in on the right side. Two large fish tend to the eggs, with other, sexually immature fish mill around the host anemone.
