Yes, fish do decompose. Like all organic matter, a fish’s body will break down over time due to bacterial and microbial activity. Decomposition can start quickly, especially in warm temperatures. This process releases nutrients back into the ecosystem. If a fish dies in an aquarium, it’s important to remove it promptly to prevent water contamination and potential harm to other aquatic life. Regular tank maintenance helps avoid such issues.
