The popular "Mickey Mouse Goldfish" is actually a species known as the Mickey Mouse Platy, and its distinctive pattern is entirely natural, not the result of artificial dye. The confusion often arises because some unscrupulous sellers do artificially color other types of fish, an unethical and harmful practice.

In a healthy aquarium, nitrite levels should always be zero, but sudden spikes can lead to fatal 'brown blood disease' in fish. Learning how to lower nitrite levels quickly is a critical skill for any aquarist, as swift action can prevent a tank-wide tragedy. Nitrite is highly toxic because it prevents fish blood from carrying oxygen, causing them to suffocate internally even with proper aeration.
