Questions tagged [algae]

Photosynthetic microorganisms that grow in wet environments. Algae are not plants, but large growths can sometimes resemble them superficially. Pet owners may encounter algae as a cosmetic nuisance, a food source for herbivores, a water quality problem, or even symbiotic growth within an animal (most often corals). This tag will often be used in the context of an aquarium or pond, but not exclusively.
