Tiny White Bugs on a Plant Near an Aquarium: Springtails, Not Aphids

A plant kept in water atop an aquarium developed minute white specks. The owner feared they'd invade the tank. The expert identified them as springtails (Collembola)—harmless, moisture-loving hexapods that feed on fungi and decaying matter. They don't harm fish or plants.

Springtails are common in damp potting media. The aquarium cleaning was prudent but likely unnecessary. If the bugs were truly stationary and speck-like, they might be fungal spores, not insects. A magnifying glass helps distinguish: springtails jump when disturbed; spores don't move.

No treatment needed—just reduce excess moisture and ensure good air circulation around the plant.
