Protein. There are foams and oils that form in an aquarium which are caused by proteins. Protein foam or oily biofilms are created when waste proteins, fish waste, decaying debris, deceased aquatic life, or natural oils from food attach to small air bubbles.
Why is my aquarium full of tiny bubbles?
Bubbles can appear in your tank due to the aquarium plants. As the plants grow and absorb light, they give off oxygen due to photosynthesis. The oxygen will sit on the leaves as little jewel-like bubbles. This is known as pearling, and it can be a sign of a healthy aquarium plant.
Why are there so many tiny bubbles in my aquarium?
Aquatic plants produce oxygen as they undergo photosynthesis. The oxygen may sit on the leaves in the form of small, jewel-like bubbles. This is called pearling and it is a sign of a healthy aquarium. Fast-growing plants will do this more easily than slow developers.
